Critical analysis of lean construction maturity models: a systematic literature review
(2023-04-21) Jayanetti, JKDDT; Perera, BAKS; Waidyasekara, KGAS; Siriwardena, M
Lean construction (LC) is becoming prevalent, and assessment of the level of LC implementation is vital for organizations to realize their full potential. In meeting that need, lean construction maturity models (LCMMs) play a key role. However, there is less evidence of critical reviews in spite of the significant number of LCMMs available. Therefore, this study was initiated with the aim of systematically reviewing the literature on existing lean-construction-related maturity models (MMs) through a critical review. The study adopted the PRISMA method to review 24 such models using manual content analysis. The study revealed the most common attributes among the models, along with their key strengths and weaknesses. The findings of this study can be directly used to develop more robust LCMMs and enhance the knowledge base on theoretical underpinnings. From an industry perspective, the findings assist organizations to more effectively assess LC maturity. The study invites further research on the area of LC maturity and advocates for developing new MMs addressing these areas identified for improvement.

Defining a ‘maturity model’ in the construction context: A systematic review
(Ceylon Institute of Builders - Sri Lanka, 2022-06-24) Jayanetti, JKDDT; Perera, BAKS; Waidyasekara, KGAS; Sandanayake, YG; Waidyasekara, KGAS; Gunatilake, S
A maturity model is critical in analysing an entity as it evaluates the current situation and provides insights on enhancing the capabilities to reach higher maturity. Maturity models are being used in many industries and proven to have a positive impact on organisational development. Definition of a context specific maturity model is vital as it brings clarity to the model identification and better understanding relevant for a respective industry. Even though several construction maturity models exist, a clear and a comprehensive definition is not noticeable. A comprehensive definition for maturity models in construction sector would assist industry stakeholders to understand the components and key areas of construction maturity. Consequently, it would provide accurate and impactful results for construction firms to achieve higher maturity levels. Thus, the main aim of this paper is to establish a new definition for construction maturity models. In the process, the methodology included a systematic literature review adopting PRISMA literature review method and a content analysis using thematic analysis. The study analysed fifteen construction maturity models and identified nine overarching themes which were fundamental in developing the definition. The proposed definition would facilitate a better understanding among end users of construction maturity models, and it would assist the readers to distinguish it from other various models. Therefore, the derived definition would promote application of the concept of construction maturity in the industry. Further research could be conducted for diverse types of construction to enhance the effectiveness of the maturity models

Key attributes of construction maturity models: a systematic review
(Ceylon Institute of Builders - Sri Lanka, 2023-07-21) Jayanetti, JKDDT; Perera, BAKS; Waidyasekara, KGAS
Maturity Models assist organisations to evaluate their existing capabilities. A key component of a maturity model is its attributes which govern the assessing criteria of the model. Several construction maturity models exist in various platforms, however, there seems a noticeable gap in the literature on existing maturity model attributes and a model template for construction sector. Therefore, to fill that gap, this study aimed at reviewing the existing construction maturity model attributes. PRISMA literature review technique was adopted to systematically review the existing, construction related maturity model attributes. The identified attributes were analysed using thematic analysis method. The study used twenty prominent construction maturity models to identify their key attributes. These attributes were analysed, and 13 key themes were derived that described model attributes. This study summarised all the literature findings on significant existing model attributes and established the foundation on how to derive attributes relevant to construction maturity models. Further, this study adds to the body of knowledge on construction maturity model attributes and opens up avenues to develop more robust maturity models. This study contributes to the practice by encouraging the use of maturity models and attributes to enhance the existing maturity of construction firms. The results of this study can be directly used by industry practitioners to establish best practices within the construction projects. Further research is encouraged on identifying additional components of models and testing the effectiveness of the findings with empirical data in future studies.

(Department of Building Economics, 2024) Jayanetti, JKDDT; Perera, BAKS; Waidyasekara, KGAS; Sandanayake, YG; Waidyasekara, KGAS; Ranadewa, KATO; Chandanie, H
Lean construction has emerged as a transformative force, seeking to enhance efficiency, minimise waste, and streamline project delivery processes. Despite global recognition and adoption, lean construction maturation exhibits variances across diverse contexts. In Sri Lanka, lean construction remains at an early stage of development. Given the nation's challenges in the construction sector and evolving project management methodologies, Sri Lanka offers a distinctive setting for exploring the maturity of lean construction principles. However, insufficient methods of investigating lean construction maturity in the Sri Lankan context have led to limited adoption of lean practices within the construction sector. Therefore, this study aims to investigate the relevant parameters for assessing lean construction maturity in the context of Sri Lanka. Adopting an interpretive stance, the study employed a qualitative research approach with semi-structured interviews using the Delphi technique. A total of 25 lean construction experts were selected through purposive sampling and 73 interviews were conducted in three Delphi rounds. Findings revealed 18 key lean construction parameters and definitions were developed conforming to Sri Lankan context. The study provides actionable insights for practitioners including identifying relevant lean practices and guidance on lean implementation, enabling them to enhance practices, improve efficiency, reduce waste, and make informed decisions through tailored initiatives and strategies. This study enhances the global understanding of lean construction maturity by identifying lean construction parameters conforming to Sri Lanka, contributing to the existing theory and filling a literature gap.

Integrating lean learning practices in construction is paramount for elevating project quality, thus bolstering industry competitiveness and sustainability. However, there exists a notable dearth of research addressing lean learning practices specifically within the Sri Lankan construction industry. Therefore, this study aims to investigate the state-of-the-art lean learning practices in the Sri Lankan construction industry. An interpretivism stance is adopted, and a qualitative research approach is used. A case study strategy was adopted, focusing on three large Sri Lankan contracting organisations selected through purposive sampling. Data was collected through semi-structured interviews with fifteen experienced individuals, and document reviews. The collected data was then analysed using code-based content analysis using NVivo 12. Different lean tools, including Last Planner System (LPS), Value Stream Mapping (VSM), and 5S, are presently being utilised in an ad-hoc manner within contracting organisations. Comprehensive lean learning practices, including regular training sessions, workshops, and hands-on exercises, were emphasised to translate theoretical lean concepts into practical knowledge. By identifying the ad-hoc nature of their implementation, the study shed light on the importance of structured lean learning initiatives tailored to different organisational levels. It is recommended to implement clear communication channels, ongoing training, and a culture of continuous improvement for sustaining lean transformation in the Sri Lankan construction industry. By focusing on lean learning practices, the topic acknowledges the continuous improvement aspect of lean construction, emphasising the need for ongoing education and skill development within construction teams. This study has the potential to contribute valuable insights to both academia and industry practitioners seeking to enhance efficiency, quality, and sustainability in construction projects.
