An Introduction to Set Based Design

Set-based Design (SBD) is a design methodology that has many applications in the architecture, engineering, and construction (AEC) industry. It was discovered when researcher studied the engineering and design process at Toyota [1]. Known as the “second Toyota paradox”, the researchers were surprised to find that Toyota considered a broader range of possible decisions, produced more physical models, delayed key decisions longer, and yet they had the fastest and most efficient vehicle development cycle in the industry.

Lean Tools During Design & Preconstruction – IPD or Not

I wanted to start this blog post with the most important message I have for all those who read this – you don’t need to have an IPD project in order to successfully use lean tools during design and preconstruction! As you will see from the real life examples described later, in order to do so, all that’s needed is the right integrated environment.

Applying Lean Thinking to the Design Process

By nature, the design process is complex; it often involves thousands of decisions, sometimes over a period of many years, with numerous interdependencies, and under a highly uncertain environment. Design can involve a large number of participants and decisions makers, trade-offs between multiple competing design criteria with inadequate information, and intense budget and schedule constraints. The influence of the design phase on the outcome of any projects both technically and economically is immense. It is in the design phase that the customer’s ideas and speculations are conceptualized into a physical model, and the customer’s needs and requirements are defined into procedures, drawings and technical specifications.
