6: Vee-Models, Scrum, and the Need to Fix Systems Engineering

A: Product-Driven Information Systems

The car in your driveway has 20,000 components, and the plane on the tarmac has a million. The development of modern products begins with thousands or millions of requirements, all of which must be managed through the stages of the product lifecycle.


This lecture briefly discusses early-stage requirements management using the Vee-model, SysML, and RFLP, as well as later-stage information structures known as Digital Twins and Threads.


Here are some links to technology vendors videos on some of the topics (under 4 min). I don't promote any one over another, but they provide some context.

B: How do we fix Systems Engineering? (by Mike Griffin)

Dr. Michael Griffin was Nasa administrator, Undersecretary of Defense in Research in Engineering, and had a long history in the US Space program. The following is from a speech given in 2010, and is assigned reading for the course. A video of Dr. Griffin's speech is below.

C: How do we fix Systems Engineering? (by Pat Hillberg)

Decomposing problems into small manageable pieces inevitably leads to dysfunction, which in turn leads to either scandalous products, or a failure to innovate. Our Systems Engineering tools are not capable of modeling the economic and cultural aspects of the organizations responsible for the products. We need Systems Thinking.



D: Scrum

Discusses other project management techniques as a lead-in to Scrum, and then posits that its true value is as a means to encourage Collective Learning.


Optional: Mike Griffin Video

In the following video (optional for the course) Griffin gives this talk at the Stevens Institute of Technology. (It runs a little under an hour.)

2: What is Product Lifecycle Management?

Pandemics and climate change lead to transformational times, which in-turn leads to new views on product lifecycles. Hint: they're circular.
