Natural hazards can have substantial destructive impacts on the built environment. Providing effective services in disaster areas is heavily reliant on maintaining or replacing infrastructure; thus, post-disaster reconstruction of infrastructure has attracted growing attention. Due to the complex and dynamic nature of infrastructure recovery projects, contractor companies engaged in this work have typically experienced poor performance. Furthermore, from a commercial perspective, the post-disaster reconstruction environment is characterized by fierce competition and market uncertainty, challenging the organizational resilience of companies undertaking this work. One approach for improving contractor performance is the implementation of lean construction, but the literature lacks consensus on its capability to affect organizational resilience. To respond to this problem, a conceptual framework applicable for lean implementation in infrastructure, which explicitly addresses organizational resilience, is required for recovery projects. In parallel, contributing components to effective implementation of lean-recovery and supportive theories for justifying the conceptual framework must be identified. Consequently, this paper proposes a conceptual framework to implement lean practices for the enhancement of organizational resilience. The framework is developed using a systematic research method, wherein 110 research documents were discovered initially, and following processing, 18 relevant documents were identified and analyzed. Through this process, contingency and Transformation-Flow-Value (TFV) theories were identified as an appropriate foundation for a framework to implement lean construction in infrastructure recovery projects.

A Conceptual Framework for Implementing Lean Construction in Infrastructure Recovery Projects

The Lean Six Sigma (LSS) philosophy and sustainability have become topics of interest since the 1990s; they have generally been analyzed together since 2012. Numerous professionals, managers, and researchers have sought methodologies by which to assess their impact and know their effectiveness within companies. During the past decade, the application of partial least squares structural equation modeling (PLS-SEM) has been widely accepted in various modeling, prediction, or multivariate analyses as a way to measure the impact of LSS on sustainability. This study conducts a literature review to identify the use of PLS-SEM in measuring the impact of LSS on sustainability. A systematic review methodology has been employed, applying five search criteria to three scientific database platforms. This approach has been helpful to identify PLS-SEM as a valuable methodology for measuring the impact of LSS on sustainability. One of the research findings is that LSS practices positively impact 83% of economic indicators, 78% of environmental indicators, and 70% of social indicators. This article creates a theoretical foundation for future research on these issues, outlining research opportunities to generate future studies. It also allows researchers and managers who are interested in improving sustainability indicators to access valuable knowledge regarding what types of LSS tools could be used.

Lean Six Sigma Impact Analysis on Sustainability Using Partial Least Squares Structural Equation Modeling (PLS-SEM): A Literature Review

Visible knowledge is a tool nearly lost in the West, but it has been used to great effect by Toyota in its 50-year march from noncompetitiveness to its current status as the second largest automobile company in the world. It is key for the 50% growth in market share Toyota plans for this decade despite worldwide overcapacity in the auto business. This book presents the reader with a systematic approach to create, capture, and display knowledge in a way that allows development teams to optimize the design of their products and production processes. Visible knowledge not only applies to knowledge management, but provides a means of collaboration to facilitate better decision-making in the development process.
This book has evolved out of a manuscript that Allen Ward, the foremost U.S. expert on lean product development, was writing at the time of his untimely death. It is not intended to be a treatise of Lean product development methods. Quite the opposite—it is focused on one small piece, "visible knowledge." It is, however, one technique that Dantar Oosterwal and Durward Sobek have found to be very effective at Harley-Davidson and other places, and a tool that can make a difference whether used by itself or as a starting point for a larger journey into Lean product development. 
In completing this work, Oosterwal and Sobek kept the aim true to Allen’s original intent. The preface and first three chapters are essentially Allen’s original intellectual contribution. They have made editorial changes to improve readability and clarity of explanation. Throughout, they have attempted to preserve Allen’s voice in the writing, even keeping the narrative in first person as it was originally written. They have also added a fourth chapter that highlights some practical ways to apply the ideas presented in earlier chapters, illustrated with case examples from their experience.

Visible Knowledge for Flawless Design: The Secret Behind Lean Product Development

Few studies have explored takt planning failures and how they might be better prevented. Recently Failure Modes and Effects Analysis (FMEA) has been proposed as a framework for actively preventing failure in takt planning projects. This project tests case study failures against the proposed FMEA framework as a first step to determine whether a FMEA-takt plan framework can help identify and respond to takt plan failures. In this case study, takt planning was implemented halfway through the construction of five large data centers in Utah, USA. The project was repetitive, enabling a takt of one day despite the large size of the project. Any variance from the schedule (a takt plan failure) was associated with a specific task and marked in their weekly work plans (WWPs). A reason for the variance was identified. These variances were compiled for all available WWPs and are compared to the failure categories proposed in the FMEA-takt plan framework. This study shows that the FMEA-takt plan framework is feasible with minor adjustments to account for failures in takt plans that are due to variables that are beyond the scope of a takt plan, such as unforeseen conditions or extreme weather.
