Using Queuing Theory and Smaller Batch Sizes to Reduce Cycle Time Locked

Research | Posted: 2007-01-12

A presentation by Jeff H. Coult, Senior Technical Manager, Honeywell AerospaceThis presentation examines two examples of the application of Lean principles to product development at Honeywell Aerospace. When faced with a bottleneck in its CAD group, Honeywell Aerospace discovered that there was little to be gained through improving its process – the issue was the queue going into the CAD group. To understand the problem more fully, the group examined a few key programs and estimated the lost sales opportunity created by the large queue – one of which amounted to about $1.5 million per month. Says Honeywell’s Jeff Coult, “The lost opportunity for that one program was enough to justify the added cost of bringing in contract help to work down the queue.” Honeywell Aerospace eventually added one full-time person to the CAD group and developed relationships with contract houses to provide temporary help as needed. The result was the elimination of the queue, the stabilization of the workload and an increase in customer satisfaction. The second example from Honeywell Aerospace addressed the concept of small batch sizes. By divided up its qualification testing into smaller “batches,” and performing these smaller test batches earlier in the process, the company was able to shave two weeks off of the qualification testing cycle.

Using External Resources to Eliminate Product Development Queues Locked

Research | Posted: 2007-01-04

By Don Reinertsen, Reinertsen and Associates Experienced product developers realize that there is a heavy price to be paid for operating a development organization at 100 percent utilization. Unless we could perfectly predict the work content of design tasks, when these tasks arrive, and the productivity of our individual development workers, such high levels of loading will cause queues in product development. Internal capacity is only one of a variety of paths to increase the capacity of the development organization. External capacity is a powerful alternative. However, using external capacity to support product development can be a little trickier than it first appears. In this commentary, Don Reinertsen discusses one of the common pitfalls of managing external capacity – the tactic known as “peak-shaving” – and how to avoid it. (3 pages)
