T&D: Revisiting My Past Newsletter Articles on ISD and PI

ISD – Instructional Systems Design – and – PI – Performance Improvement

Fall of 1999 – How a 2×4 Helped Turn Piles of Courses
into Paths of Learning

Written by Stephen Muller – a former client and then a subcontractor.


My first T&D Path design was for Manufacturing Supervisors and was done in 1981 when I was at Motorola. I needed to show a logical progression and options for my target audiences who came from one of five Business Sectors.

My next effort was for Ray Svenson and my former wife and Ray’s consulting firm – something I did during the summer of 1982 on two successive weekends while I was still at Motorola – a side gig if you will.

All of that type of ISD soon became known as Curriculum Architecture Design – CAD.

I recently finished the Analysis efforts for my 76th CAD effort as a consultant. It’s my favorite kind of ISD project – since becoming a consultant in 1982.

Here Stephen reflects on what he learned about these kinds of ISD efforts.
