Enhancing A3 Problem Solving with Technology

A3 problem solving has been popularized by the Toyota Production System [1]. At its core an A3 is simply a standard sheet of paper that is 11” X 17”. Despite its simplicity, an A3 is a powerful tool for problem-solving and communicating complex ideas in a simple manner. In this blog post we will describe the benefits of applying A3s and how technology can enhance this tried and true method.

Applying Kanban in a Small HVAC Company

This blog post is a continuation of our series on the application of Lean Construction methods in a small HVAC Company. The goal of this post is to show how a small company applied Kanban to manage their work processes. We will look at Kanban from three perspectives: 1) managing inventory, 2) managing customer inquiries, and 3) managing RFIs.

Applying the Last Planner in a Small HVAC Company

According to the US Bureau of Labor Statistics, there are 6.5 million people working in the US construction industry in 2016. The average construction worker is statistically more likely to work in a small or medium business than a large multi-billion company. Despite this statistic, many of the research and implementation case studies in Lean Construction have been on large multi-million or multi-billion projects. The goal of this blog post to present a case study of an application of the Last Planner System within a small 20-person company. Some of the following misconceptions are also addressed: 1) The Last Planner only works with large companies or on large projects, and 2) the Last Planner does not apply for short duration projects.

An A3 Template for Lean Research

In Lean Construction, we recognize that there are inherent wastes in every production system. Our objective is often to identify and reduce the wastes. Just as construction and design have been conceptualized as production systems, it can be argued that research is also a production system. Instead of producing a design or creating a product, the output of research is new knowledge. If research is truly a production system, then could we apply the same Lean methods and tools to drive out waste and improve its efficiency?

7 Ways to Make Shared Risk and Reward Sustainable in the Construction Industry

Around the world, shared risk and reward contracts are becoming more prevalent. In the United States several forms of agreements for construction projects including: Sutter Health’s Integrated Form of Agreement (IFOA), the ConsensusDocs 300, and American Institute of Architects (AIA) contracts have provisions for sharing the profit and the losses of a construction project between the owner, contractor, architect, specialty trade contractors, and other service providers.

How Target Value Design Works. A Theoretical Model

Research on Target Value Design (TVD) has found that TVD projects are delivered 15% to 20% below market price1. Additionally, TVD projects are more likely to achieve predictable cost performance outcomes while carry less contingency than projects that do not use TVD2. This post introduces a theoretical model to explain these results.

Target Value Design as a Method for Controlling Project Cost Overrun

Project cost overrun is a common problem around the world. A study of 258 projects in 20 nations revealed that cost escalation occurred in 9 out of 10 projects. The study found that on average the final cost was 28% higher than the forecasted cost. Cost overrun is a serious problem because it makes construction investment projects risky due to the unpredictability in the final cost.
