Lecture 10 - Redesign Principles and Tactics

=====================================================================

Response: 

The three generic ways for redesigning as described in the lecture can also be represented in the image below.

The reengineering principles are divided into 3 main principles around processes :

1. Restructuring and reconfiguring

2. Changing Information flows

3. Changing Knowledge management

Looking into the restructuring and reconfiguring part, there are 4 enumerated parts :

1. Lose Wait

2. Orchestrate

3. Mass Customize

4. Synchronize

Just looking into the restructuring and reconfiguring of process, the first principle is to Lose Wait. This is to reduce the waiting time inside a process. For example, the few methods for obtaining lose wait as mentioned in the lecture are concurrency, closed-loop, Not gating main process, Continuous flow, and Upstream relives Downstream. These are relatively somewhat jargon to those without any redesign processes background. 


 A couple of simple examples to illustrate these four points would better help the understanding of the principles. Given a small restaurant, an application of concurrency - lose wait- would be applicable to the cooking process. Rather than one person completing one dish from start to finish, the process would include having multiple people work on different stages of  a dish then complete it concurrently. Orchestrate in this scenario would be the finding the optimal cooked ingredients (to provide zero inventory), to reduce the whole process making it efficient through the use of commissary. Mass Customize can be applied in this scenario through Dynamic Customization. That is catering to the customers needs and what they want directly, made to order perhaps. Synchronization is one of the more straight forward tactics, it can be implemented directly from production to delivery.

Comment on Eleanor's blog week 10:

The example for applying the business process reengineering principles within health care in Canada was very concrete and informative. Not many examples exists that encompasses all 10 traits/ tactics of the total 3 main redesign principles. Furthermore, I think Eleanor did a good job of explaining how the processes worked. Some limitations include the synergy or the outlook of the redesign of the health care as a whole. Yes, I think the one-by-one explanation and application of the processes somewhat worked but I could not picture it as a whole redesign, thus it lacks in the completeness aspect.
