Cellular Manufacturing versus Group Technology
Via Scoop.it – Cellular manufacturing
Arif Nurrahman’s article presents Cellular manufacturing (CM) as an application of Group Technology (GT). This is the view of GT experts like Burbidge in Production Flow Analysis, for example, but is at odds with the Lean approach, as explained, for example, in Sekine’s One-Piece Flow, or in Lean Assembly. Group Technology creates product families based on feature similarity, ignoring the demand structure. The Lean approach is to make it easiest to do what you do most often and therefore starts by classifying products as Runners, Repeaters and Strangers based on demand. Runners are few in number but have a sustained demand high enough to justify dedicated lines. At the opposite end of the spectrum are the many Strangers with low, sporadic demand that you make in a job shop. In-between are the Repeaters, for which you use Group Technology to arrange into families for which you build flexible lines.

Thomas J. Sowell, in the Lean & Kaizen discussion group on LinkedIn, commented as follows:
Many Lean cells do not cover manufacturing operations from start to finish but only a segment of the process. This may be because some of the operations in the process are still performed on monuments that cannot be dedicated to the cell, or because the process is too long for a single cell.
One of the key characteristics of the cell concept is the small team that operates it, and it cannot exceed 8 members for the positive group dynamics to occur. If your process requires 50 operators from start to finish, you cannot run it in a single cell.
If you collocate all the resources needed for this process, you may have a focused factory, but not a cell.

[…] the functional, or job-shop, organization is not wrong for everything. Once you have done your Runner/Repeater/Stranger analysis, it is actually what you need for Strangers. And it is not always wrong in office work […]
