Introduction
The construction industry is a critical sector in global economic development, significantly influencing infrastructure projects in both developed and developing nations. This sector accounts for over 40% of global electricity consumption and approximately 30% of worldwide greenhouse gas emissions, making it one of the most resource-intensive industries. 1 In developed regions such as Europe and the United States, the construction sector’s energy consumption can reach up to 40% of total usage. 2 In contrast, in developing countries, particularly in Africa, the construction industry plays a vital role in improving living standards and is viewed as a key driver for economic diversification and growth through infrastructure and manufacturing investments. 3
However, despite its significance, the construction industry in many developing countries struggles to meet international quality standards, highlighting a need for enhanced project management practices. 4 The industry’s reliance on traditional project management methods, such as the waterfall approach, often exacerbates inefficiencies due to its rigid, sequential structure that lacks flexibility and adaptability.5,6 These outdated methods hinder the effective management of risks, delay project timelines, and limit the integration of stakeholder feedback, making it difficult to meet modern demands, particularly in sustainable construction.7,8
Agile Project Management (APM), which is known for its flexibility, iterative processes, and focus on continuous improvement, offers a potential solution to these challenges. Originally developed for software development, APM has increasingly gained attention in the construction sector due to its ability to enhance adaptability, client satisfaction, and project transparency. 9 Key principles of APM, such as self-managing teams, iterative feedback loops, and emphasis on collaboration, can improve risk management and help align project timelines more closely with project goals.10,11 Furthermore, by adopting APM, construction projects can more easily incorporate sustainable practices, which are becoming increasingly important in the face of environmental and resource challenges. 12
However, the adoption of APM in the construction industry, particularly in developing economies like Nigeria, faces several barriers. Human factors, including a lack of expertise in APM, insufficient training, and issues with team dynamics, are significant obstacles.13,14 Additionally, social factors, such as ineffective stakeholder engagement and poor communication, complicate the collaborative processes that APM relies on. 15 Economic barriers like resource constraints, fluctuating costs, and financial instability further challenge the implementation of agile methodologies. 16 Finally, cultural resistance to change, especially in industries that have long relied on hierarchical structures, remains a substantial hurdle to the widespread adoption of APM in construction.12,17
While sustainability considerations are increasingly relevant to the construction sector, and APM can support these goals by enhancing project adaptability and efficiency, this study focuses on identifying and addressing the specific barriers to APM implementation. Through a deeper understanding of these barriers, particularly in the context of Nigeria’s residential construction sector, this research aims to provide practical recommendations for overcoming these challenges and facilitating more effective project management practices.7,11
In this context, this research aims to identify and overcome barriers to APM in residential construction, thereby improving project success and sustainability. By focusing on this crucial yet underexplored area, the study seeks to deepen the understanding of how agile practices can be specifically tailored and applied effectively in residential construction.
Therefore, this study aims to achieve the following objectives: 1. Identify the significant barriers to APM implementation in the Nigerian construction industry, specifically within residential construction projects. 2. Analyze the data collected from construction professionals using Exploratory Factor Analysis (EFA) and Partial Least Squares-Structural Equation Modeling (PLS-SEM). 3. Prioritize the key barriers to APM adoption to suggest effective strategies for overcoming these barriers. 4. Provide practical recommendations for stakeholders in the Nigerian construction industry to enhance project management practices and achieve sustainability objectives.
The remainder of this paper is structured as follows: The barriers hindering the implementation of APM in construction are discussed in the next section. The research method, including data collection and case study, common method variance, construct validity analysis, measurement model, and structural model, is outlined in the following section. Data analysis is presented, addressing common method bias, exploratory factor analysis, measurement model validity (convergent and discriminant), and structural model analysis. A detailed discussion of the results follows, focusing on economic, social, cultural, and human factors. Finally, the implications of the findings for theoretical and practical perspectives are explored, and the study concludes with suggestions for future research.
Barriers hindering the agile project management implementation in construction
APM has brought about transformative changes in various sectors, especially software development, due to its focus on flexibility, efficiency, and stakeholder satisfaction. However, implementing APM in the construction industry introduces a unique set of challenges due to the sector’s inherent complexities and demands. This thematic literature review categorizes these challenges to provide a structured overview, making it clearer how each affects the adoption of APM in construction.
Project management and scheduling challenges
The agile iterative approach, beneficial in software development, complicates task scheduling within construction projects. This complexity arises as agile discourages detailed plans in the early stages, making it difficult to forecast overall project duration and impacting resource procurement. This uncertainty exposes projects to risks such as price fluctuations and scheduling issues, underscoring the importance of robust project schedules for successful execution and scope control.15,18,19
Economic and financial constraints
Agile methodologies introduce a level of unpredictability in project costs and schedules due to their flexible nature, which can accommodate changes but also lead to economic challenges like price fluctuation. These issues require a careful balance between the inherent flexibility of agile methods and the defined project scopes, budgets, and timelines critical to the construction industry, highlighting the economic tensions faced in APM.18,20
Human factors and team dynamics
Effective collaboration and communication are central to the success of agile projects, which emphasize the human element over strict processes. However, implementing agile principles in construction, especially in large teams, introduces additional coordination challenges due to limited interaction among participants and complex interdependencies. These factors complicate the fostering of effective collaboration in traditionally hierarchical environments.15,21
Cultural and organizational barriers
Adopting agile methodologies requires overcoming significant cultural and organizational barriers, including resistance to change rooted in long-held values and traditional power dynamics. This resistance is driven by fear of the unknown and a sense of loss of control, necessitating a fundamental shift in team engagement, decision-making, and prioritization. Such changes challenge established organizational structures and routines, requiring extensive training and reassurance to facilitate the adoption of agile principles.22–24
Client and external stakeholder engagement
Managing client expectations under agile methodologies poses considerable challenges as clients may have predefined expectations regarding project scope, budget, and timing that do not align with the iterative and adaptive nature of agile. Regular involvement and open communication are necessary to educate clients on the benefits of flexibility and adaptability, making stakeholder management a critical yet challenging aspect under agile methodologies.22,25,26
Regulatory and technological challenges
The adoption of agile in construction must navigate regulatory and contractual constraints that demand a compromise between agile flexibility and the industry’s stringent requirements. This often involves adjusting agile practices to incorporate necessary documentation and compliance measures, alongside renegotiating contracts to accommodate an agile approach. Additionally, the lack of advanced tools and technology tailored for agile project management in construction hampers effective implementation.27,28
Knowledge management and documentation
Agile practices encourage less formalized communication channels and minimal documentation, which can disrupt traditional power dynamics and make it difficult for organizations to maintain control over project information. The challenge of knowledge management is compounded by the need to balance adequate documentation, which is essential for maintaining clarity and continuity, with the agility required in agile projects. This balance is critical to ensuring that agile projects remain responsive to change while providing a reliable framework for project execution.29,30
Summary of barriers affecting the adoption of APM in construction.
Research method
Figure 1 provides a visual representation of the research design. The literature review, summarized in Table 1, identified 16 significant obstacles hindering APM effectiveness. Following this, a questionnaire survey was distributed among residential construction professionals with relevant industry experience, aiming to gather insights into barriers to APM. EFA was employed to assess the comprehensiveness and clarity of the identified APM barriers. EFA was chosen due to its ability to identify underlying relationships between observed variables and reduce data complexity, which helps in grouping the barriers into coherent factors. This method was applied to ensure that the barriers were well-defined and to refine the factors used in subsequent analyses. For determining the significance of the APM barriers, PLS-SEM was used due to its suitability for handling complex models with multiple constructs. This method was chosen due to its ability to handle both formative and reflective measurement models. It is particularly valuable in research fields where the theoretical knowledge is still developing, as it allows for greater flexibility in modeling complex relationships. In recent years, this method has attracted considerable attention across various fields, notably in business research and social sciences.
43
In this study, the latest version of SMART-PLS 3.2.7 was utilized to perform the analysis, evaluating both the measurement model and the structural model. Research design.
Data collection and case study
Demographic profile of survey respondents.
To collect this data, we employed two non-probability sampling methods: purposive (judgment) sampling and snowball sampling. Purposive sampling was particularly efficient and cost-effective, enabling the selection of participants directly involved in or knowledgeable about APM in the construction sector. Conversely, snowball sampling expanded our coverage by leveraging the networks of initial respondents, who recommended additional professionals. This method effectively broadened the diversity of viewpoints by creating a referral network that enriched the study’s data set.
The survey was structured into three sections: (1) respondents’ demographic information; (2) inquiries about the APM barriers listed in Table 1; and (3) open-ended questions to identify any barriers deemed crucial by the respondents. The APM barriers were evaluated using a 5-point Likert scale, with 5 indicating “extremely high”, 4 signifying “high”, 3 meaning “moderate”, 2 signifying “low”, and 1 indicating “none or very low.” The questionnaire used in this study was developed based on an extensive review of the literature on APM and its barriers in the construction industry. Key themes and constructs were identified from previous studies and used to design the survey items. To ensure content validity, the initial draft of the questionnaire was reviewed by a panel of five experts in the field, including three academic researchers specializing in construction management and sustainability, and two senior professionals with over 10 years of experience in construction project management. Their feedback was incorporated to refine the questions and ensure they were clear, relevant, and comprehensive.
To further ensure the reliability and validity of the instrument, a pilot test was conducted with a small sample of 15 construction professionals from different roles (contractors, consultants, and engineers) in the industry. The results of the pilot test were used to assess the clarity, relevance, and appropriateness of the questions. Based on the feedback from the pilot test, minor adjustments were made to improve the clarity and structure of several items. The final version of the questionnaire consisted of 25 closed-ended questions evaluated using a 5-point Likert scale, along with two open-ended questions to capture any additional barriers the respondents deemed relevant.
To determine the appropriate sample size, the methodological analysis recommended by Badewi 44 suggested that a sample size exceeding 100 was suitable for survey studies. A total of 109 responses were obtained from 120 individuals, resulting in a response rate of 90%. This response rate was considered satisfactory based on the findings of previous studies.45,46
While the demographic diversity of the sample provides valuable insights, the sample size of 109 respondents may not fully represent the broad construction sector in Nigeria. Future research could enhance the generalizability of the findings by incorporating a larger and more varied sample, possibly including respondents from additional sectors or regions within the country.
Common method variance
Common Method Bias (CMB) was assessed by calculating Common Method Variance (CMV). CMB serves to highlight inaccuracies in research findings that stem from the measurement method used rather than the constructs the measures are intended to represent. This emphasis on the measurement method differentiates CMB from the constructs. Additionally, CMV can be viewed as an overlap in variance attributable to both the constructs under study and the types of measurement instruments utilized, offering an alternative perspective on CMV. The issue of CMV becomes particularly acute in cases where data collection relies on a single source, such as responses gathered from a questionnaire.47,48
In some instances, the use of self-report data may either amplify or diminish the scope of the relationships under study, thereby introducing challenges.48,49 This issue becomes particularly pertinent when considering that all data is derived from subjective self-reports and originates from a singular source. Hence, addressing these challenges in identifying common method modifications is crucial. The systematic one-factor test ascertains whether factor analysis reveals a solitary factor responsible for the majority of the variance. 48
Construct validity analysis
Factor analysis is typically conducted using either Confirmatory Factor Analysis (CFA) or EFA. In this study, CFA was utilized to assess the structure underlying the various variables proposed in the hypotheses and theories. Conversely, EFA is applied to explore the relationships among multiple variables and simplify numerous variables into fundamental structures.
50
EFA is designed primarily for data that are either interval or ordinal. A scatterplot was used to demonstrate the degree to which the variables were partially or fully related. This method aims to simplify analysis by reducing the number of components, thereby representing a set of variables with fewer dimensions. The equation employed in the EFA process is shown in equation (1).
In this equation,
EFA is a pivotal multivariate analytic technique that facilitates the investigation of the underlying structures within APM barrier elements. Its application is critical for evaluating the constructs’ measurement items in terms of unidimensionality, reliability, and validity (i.e., measurement models). Notably, Principal Component Analysis (PCA) was preferred over alternatives such as principal axis factoring, image factoring, maximum likelihood, and alpha factoring, owing to its enhanced precision and reduced complexity. 51
When EFA suggests possible solutions without an existing theory or model to support them, PCA emerges as an advantageous approach. 50 Thompson 52 noted that PCA’s adoption as a default in numerous statistical software makes it a common choice for conducting EFA. The research opted for a varimax rotation instead of simpler rotations such as oblimin or Promax, aiming for an equitable distribution of workload among variables. Varimax rotation is praised for its ability to improve factor clarity, making it an excellent choice for basic factor analysis. 53 A sample size of 119 and the inclusion of 17 variables were deemed adequate for the factor analysis process. 54
Measurement model
The measurement model reveals both the latent structure of the items and their existing relationships.
55
The following sections comprehensively examine the convergent and discriminant validity of the measurement model. • •
Structural model
This study applied SEM to identify the most significant barriers to APM. The critical step involves calculating the path coefficients among the observed variables. It was hypothesized that £ (structures of APM barriers) directly influence µ (implementation barriers of APM). A linear equation, represented in equation (2), was utilized to illustrate the internal dynamics between the £, µ, and €1 structures within the structural model.
60
In this context, (β) represents the path coefficient connecting the constructs of APM barriers, with the residual variance in this structural layer assumed to be captured by (€1). The standardized regression weight (β) was analogous to the β coefficient in the multiple regression analysis.
The pivotal aspect of this analysis was the evaluation of the significance of the path coefficient (β). Similar to the processes used in CFA, this investigation calculated the path coefficients’ standard errors using a bootstrapping technique available in SMART PLS 3.2.7 software, as per the recommendations of, 43 the generation of t-statistics for hypothesis evaluation utilized 5000 bootstrap samples. Within the PLS model, equation (2) was employed to develop four structural equations related to the constructs of APM barriers, each detailing the interrelationships between these constructs.
Data analysis
Common method bias
CMB, a measurement error variance, threatens the validity of research findings by introducing systematic errors in both measured and predicted variables. 53 The extent of this bias can be determined using Harman’s single-factor test, which assesses various structural elements. 62 This research applied a single-factor test to assess the standard deviation. 63 If the aggregate variance explained by the factors is less than 50%, this suggests that CMB may not significantly influence the results. Given that the initial group of components explains only 32.0% of the total variance, it is evident that the results are unlikely to be distorted by the CMV, remaining below the 50% threshold. 62
Exploratory factor analysis
EFA was employed to investigate the factor structure of 16 items related to barriers to APM. This analysis utilized several widely recognized measures of factorability. Typically, the Kaiser-Meyer-Olkin (KMO) measure is applied to assess the adequacy of sampling for factor analysis by ensuring that the partial correlations among variables are minimal.
64
For factor analyses to be deemed acceptable, the KMO index must exceed 0.6.
65
Furthermore, Bartlett’s test of sphericity confirms the non-suitability of the identity matrix as a correlation matrix at a significance level of
Kaiser-Meyer-Olkin and Bartlett’s test coefficients of the barriers.
Additionally, Table 3 reveals a

Reliability metrics were established for the factors identified through EFA. The assignment of variables to each factor was based on the highest loadings within the structural matrix. According to Ref. 58, a Cronbach’s alpha value of greater than 0.6 is required for newly developed scales. Conversely, an average value of 0.7 suggests that values exceeding 0.75 are deemed highly reliable. Given that Cronbach’s alpha values exceeded 0.6, the results can be considered dependable. Furthermore, the average correlations among items exceeded 0.3, demonstrating consistent internal coherence among variables.
Measurement model
In SEM-PLS analysis of reflective measurement models, it is essential to assess internal consistency, convergent validity, and discriminant validity. Once the validity and reliability of the measurement model are confirmed, an evaluation of the structural model follows. 60

Upon identifying the APM barriers as a formative construct, the analysis assesses collinearity among the constructs’ formative indicators by examining the variable inflation factor values. With all variable inflation factor values significantly below 3.5, each subdomain contributes independently to the overarching construct. Additionally, bootstrapping was employed to evaluate the significance of path coefficients, with results showing statistical significance at the 0.01 level for all paths.

Discussion
Although APM in the construction sector is extensively utilized in many developed countries, its adoption in developing nations, including Nigeria, is just starting to emerge. The construction quality in these emerging economies faces various challenges and contradictions. The introduction of new methodologies is expected to markedly influence the construction sector; however, assessing the impact and potential advantages of APM remains challenging. 70 Therefore, the application of APM principles is crucial to address these challenges. The likelihood of senior management endorsing the integration of APM into project frameworks increases when practitioners are well-informed about APM and its critical construction processes. The proposed model identifies four key dimensions of APM that have a significantly positive influence on its adoption. This adoption is intended to enhance the sustainability of residential construction projects. Consequently, adopting APM can lead to cost and time savings while elevating the quality without compromising the essential functions of the project. The subsequent sections detail the use of the PLS-SEM model to prioritize barriers to APM adoption.
Economic
The significance of building project characteristics cannot be overstated. According to the PLS-SEM model, the “economic” factor, with an external coefficient of 0.516, is identified as having the most substantial influence on the barriers to APM implementation. This factor encompasses 10 elements: task scheduling, scope monitoring and control, fluctuations in pricing, knowledge management issues, cost and time management issues, challenges with large project teams, difficulties in applying APM to large-scale projects, implementation during the construction stage, pre-completion testing challenges, and complications making changes during the construction phase. This insight aligns with, 18 who asserted that scheduling project tasks presents a notable hurdle for APM. Agile methodology advises against setting fixed specifications and plans at the outset of a project, which complicates quality assurance and control owing to the absence of predefined benchmarks for monitoring and validation. Similarly, Owen et al. 35 found that although agile methodologies are applicable in the pre-design and design stages of construction projects, their adoption faces significant obstacles in the construction phase. Furthermore, Xu 32 highlighted severe coordination issues in implementing agile principles within large-scale projects attributed to limited participant interaction, communication challenges, technical complexities, and intricate task interdependencies. The use of agile methodologies in sectors beyond IT, engineering, and product development presents significant challenges.
Social
“Social” factors were identified as the second principal component, encompassing obstacles such as construction professionals’ lack of awareness, regulatory and contractual limitations, scarcity of construction-experienced agile practitioners, insufficient tools and technology for APM application in construction, challenges in documentation and reporting, and stakeholder management. This observation corroborates the view that construction personnel, who are typically more familiar with conventional project management techniques, might not be well-acquainted with agile methodologies prevalent in software development. 42 This unfamiliarity can hinder the effective adoption of agile practices in construction projects. A significant impediment is the overall dearth of agile methodology expertise and exposure in the construction sector. Traditional project management methods are the foundation of most construction professionals’ training, leaving them with little or no exposure to agile principles during their education or career development.
Cultural and expectations
The third key component pertains to “cultural and expectations”, addressing obstacles such as the transformation of entrenched organizational cultures and managing client expectations, with two items specifically mentioned. This insight is in line with 39 analysis, which suggests that the adoption of agile methodologies requires a significant shift in team interaction, decision-making, and prioritization processes. Such changes can challenge existing organizational frameworks, communication paths, and traditional norms, leading to resistance and hindrances. Furthermore, Ciric et al. 25 highlighted that aligning APM with client expectations poses a substantial challenge. Agile methods, owing to their iterative and flexible nature, may not align with clients’ conventional expectations regarding project scope, budget, and timelines. Given that clients may hold specific preconceived standards and may not be well-versed in agile practices, ensuring that their expectations are met and managed is crucial.
Human
The fourth category in the hierarchy of obstacles to APM implementation is labeled “knowledge”, with an external coefficient of 0.138. This category encompasses barriers including deficiencies in awareness and market understanding. Human factors in APM can be broadly understood within the framework of socio-technical systems, which integrate social and technical elements. Previous research has extensively explored these systems, highlighting various aspects of human factors in different contexts. For instance, Ogbeyemi et al. 71 investigated human factors among workers in small manufacturing enterprises, while Aloui and Shams Eldin 72 examined socio-emotional competencies and their impact on employability. The scant awareness of APM constitutes a significant impediment to its integration into the construction sector, particularly in emerging economies. This issue may stem from negative perceptions of new technologies. 73 It is challenging for new technological solutions to gain recognition in the construction industry. 74
This study identified several key barriers to APM adoption in Nigeria’s residential construction sector, focusing on economic, cultural, and human factors that hinder both project success and sustainability efforts. The findings suggest that economic factors such as price fluctuations and cost management challenges are the most significant barriers to APM implementation. Cultural factors, including resistance to change and entrenched organizational norms, as well as human factors like inadequate collaboration and lack of APM awareness, also play critical roles in limiting the adoption of agile practices.
These findings align with and extend prior research on APM implementation in various sectors, while also highlighting unique barriers specific to the construction industry in developing economies. Previous studies, such as those by Owen et al. 35 and Xu, 32 identified the challenge of integrating APM into large-scale projects, particularly in traditional industries like construction, where rigid structures dominate. Our results are consistent with these findings, particularly the economic and human factors that hinder the flexibility required for agile practices. For instance, the economic barriers identified in this study, such as price fluctuations and cost management challenges, reflect the unpredictability that Owen et al. 35 also observed as an obstacle to agile adoption during the construction phase.
Furthermore, Ciric et al. 25 emphasized cultural resistance as a significant barrier to APM implementation in construction, which is supported by our findings. In Nigeria, entrenched organizational cultures and general resistance to change were identified as critical challenges, reinforcing the literature that highlights the difficulty of transforming hierarchical structures in traditional industries to accommodate agile principles. This cultural barrier is particularly pronounced in developing countries, where familiarity with APM is still growing, as Taylor 26 observed in her study on the transition to agile methodologies.
However, our study also extends previous literature by focusing specifically on sustainability in construction. While Masood and Farooq 15 explored the benefits of agile practices in promoting flexibility, our findings emphasize the additional challenges posed by the integration of sustainability objectives within APM frameworks. For example, economic and regulatory barriers not only affect the agility of project management but also directly impact the ability to meet sustainability goals, particularly in resource-constrained environments like Nigeria. This gap in previous research highlights the need for a more nuanced understanding of how APM can support sustainable construction, which is a critical concern for developing countries.
Our findings also diverge from some prior studies in terms of the social and human factors influencing APM adoption. While Boehm and Turner 36 noted that agile methodologies are highly adaptable to sectors involving frequent stakeholder interaction, the limited awareness and expertise in APM among Nigerian construction professionals pose a unique challenge. This suggests that APM frameworks developed in more mature markets might require significant adaptation when applied to the construction sectors of developing economies.
By situating our results within the broader context of APM literature, this study not only reinforces existing theories but also highlights new areas for future research. Specifically, the intersection of APM, sustainability, and construction in developing countries presents opportunities to explore how agile practices can be tailored to meet both economic and environmental goals.
Implications
Theoretical implications
This study makes significant contributions to the existing body of knowledge on APM and sustainable construction, particularly in the context of developing economies. While APM has been extensively studied in software development and other sectors, its application in the construction industry, especially in emerging markets like Nigeria, is underexplored. This research fills a critical gap by identifying specific barriers to APM implementation in the construction sector and examining how these barriers affect sustainability outcomes. Furthermore, the study extends existing theories by integrating the concepts of sustainability and APM, providing a new lens through which future studies can assess the relationship between agile practices and sustainable construction. This study’s findings also offer a foundation for developing theoretical frameworks that address the intersection of APM, project success, and sustainability in resource-constrained environments.
Practical implications
From a practical standpoint, the findings of this research have direct applications for policymakers, construction managers, and industry stakeholders. The identified barriers to APM adoption—such as economic, social, cultural, and human factors—provide a roadmap for decision-makers to address these challenges in real-world projects. By understanding and mitigating these barriers, construction firms can enhance project outcomes, improve cost efficiency, and promote sustainability in their operations. The recommendations for overcoming economic constraints and fostering greater collaboration and communication within teams are particularly relevant for achieving sustainable practices in the construction sector. Moreover, this study’s insights offer actionable guidance on how to integrate APM methodologies in developing countries, enabling more effective project management and contributing to the broader sustainability agenda. These contributions are essential for the construction industry to achieve better project delivery, cost reduction, and long-term environmental responsibility.
Conclusion
APM has been widely recognized for its potential to optimize value, project outcomes, and sustainability, particularly in large-scale construction projects. However, its adoption in developing economies, including Nigeria, remains limited. This study examined the barriers hindering the APM implementation in Nigeria’s construction industry. Through an extensive literature review, we identified 16 critical barriers, which were subsequently refined using EFA and empirically validated through PLS-SEM. Data gathered from 120 construction professionals in Nigeria highlighted key obstacles to APM adoption and provided a foundation for overcoming these challenges.
The findings of this study contribute to both academic and industry practice by offering a framework of barriers to APM within the Nigerian construction sector. The results have significant implications for improving project delivery, reducing costs, and promoting sustainability through targeted APM strategies. The timing of this study is particularly critical, as Nigeria’s construction industry is currently experiencing rapid growth and facing increasing pressure to deliver sustainable housing solutions. Therefore, this research serves as a timely intervention to guide industry professionals toward adopting APM strategies that can address these demands. Despite these contributions, several limitations should be acknowledged: 1. Sample size and representation: The study’s sample size of 120 respondents, while providing valuable insights, may not fully represent the diverse range of stakeholders in the Nigerian construction industry. Future research could benefit from a larger and more varied sample to enhance the generalizability of the findings. 2. Data collection methods: The data was collected through a questionnaire survey, which may introduce biases such as self-reporting bias or response bias. These biases could affect the accuracy of the insights into APM barriers. Utilizing multiple data collection methods, such as interviews or case studies, could provide a more comprehensive understanding. 3. Regional focus: The research focused specifically on Nigeria, and the findings may not be directly applicable to other developing countries with different construction industry contexts. Comparative studies involving multiple countries could offer a broader perspective on APM adoption challenges.
Acknowledging these limitations provides a more balanced view of the study’s conclusions. Future research could address these limitations by employing larger and more diverse samples, incorporating multiple data collection methods, and exploring the broader implementation of APM in construction projects. Continued research and exploration in this field will contribute to advancing APM practices and enhancing sustainability in the construction industry.
