Asphalt is a black, semi-solid form of petroleum used to bind aggregate together. Asphalt’s most common use is to form smooth, durable surfaces for roads, driveways, walking paths, and parking lots. Lean and Six Sigma methods aid production and use of asphalt and paving. We’ll look at applications from Thailand, the USA, and Lebanon and [...]
Welding processes are used around the world in a range of industries including aerospace, automotive, energy, construction and many others. Lean and Six Sigma methodologies are used to improve the quality of the welds and the associated processes. We’ll look at three applications from Pakistan and India, and see how to implement Lean in welding [...]
The modular construction market is projected to grow from $75.89 billion in 2021 to $114.78 billion in 2028 at a compound annual growth rate of 6.1% during 2021-2028 mainly due to the benefits of reduced waste, building speed, flexibility, and cost-effectiveness. Lean methodologies are playing a part in helping that growth. We’ll take a look [...]
The making of cement is a production process. It is natural then that Lean and Six Sigma can be used to improve that process and those associated with the making of concrete where cement is a key ingredient. We’ll look at case studies from Bangladesh, Egypt, and Saudi Arabia and a thesis on the benefits [...]
