Integrating Agile, Scrum, and LPS Principles: the Development of a Hybrid Agile Lean (HAL) Production Planning & Control System

This study proposes a Hybrid Agile Lean Production Planning and Control System that synthesises the theoretical and practice-led attributes of Last Planner System, Takt, and Scrum.The research was motivated by a question in the 2020 Benchmark: Can "agile" methods augment the LPS?The study is qualitative in nature employing mixed methods and consists of nine case studies on Agile, Scrum, Last Planner System, and Takt used on projects in Ireland.Interviews were conducted, and the data was analysed through thematic analysis and merged with findings from documentation, observation, and focus group workshops.Implementation of Last Planner System was examined across several projects and enhancements were introduced to address known shortfalls.Takt in construction was explored and a study presented improved delivery outcomes when Takt complemented Last Planner System.Scrum and Agile's applicability to construction was reviewed and studies examined Agile in the design process, Scrum complementing Last Planner System, and Scrum complementing both Last Planner System and Takt was evaluated in a combined Hybrid Agile-Lean Production Planning and Control System.This study builds on the Author's previous work and culminates in an artifact that synthesises Critical Path Methodology, Last Planner System, Takt, and Scrum into a single planning system.Future research should focus on assessing the HAL System across other construction sectors like infrastructure.
