Choosing reliability growth model for open source software, online first from IEEE Computer

Link to full text at IEEE

Predicting the number of unknown defects has always been an important problem to solve. A lot has been done in the area and a lot will be done before the problem is solved.

This paper highlights different types of reliability models (e.g. Convex, Concave) and how to choose between them for open source projects. It’s a magazine article so it reads nicely and gives useful pointers. Recommended as Friday evening reading:)

Measures for the Lean Start-ups

During my development of course material for DIT595 (Industrial Best Practice) for the Bachelor Program in Software Engineering and Management I got inspired by the Lean Start-up by Eric Ries (Crown Business Publishing, theleanstartup.com). The book is a very good material for entrepreneurs willing to start their own businesses. It is also very good for our students who want to do their bachelor and master theses in industry.

I also did some extra search for more articles on how measuring should be done in the lean start-ups. I have found the following article with tips for creating metrics – 8 tips…. The article proposes the following:

    • Be actionable
    • Be understandable and trustworthy
    • Measure results
    • Understand the downside
    • Understand the upside

Since the article is free I will not quote more – I recommend reading it and reflecting upon the metrics that we create.
