PM Guidance References - Regression Testing
Does anyone have recommended information sources for managing regression testing on large complex projects?

I am starting an assignment transitioning high level process guidance into end-to-end standard practices, including change board, vendor management, verification and validation, etc. The changes involved include both hardware and software.

I have current state info for existing processes, and I have started searching for relevant industry literature, but if anyone has sources they personally recommend it would be greatly appreciated.

Hi Keith,

Please check this - https://www.globalapptesting.com/regression-testing-guide

Regression testing is key gate keeper specially for larger and complex projects. It is wise to perform thorough peer review / brainstorming session among team and come up with Lean workflow that can cover all functional area of application. Hope the above article will help you to some extend, eventually it also depends on the project landscape on what is idea scope of Regression Coverage.

Thanks.

Thank you Sabir. That article gave me some interesting thoughts. Perhaps most significantly that regression testing strategy should consider the up-front change process and minimal disruption. If the verification process is an afterthought then we must simply deal with the problems reactively. To miimize this, the regression testing process needs to start upstream to proactively manage the amount of disruption when considering the implementation plans.
Hi Keith, perhaps I did not answer your question but in my case we are using R as support to analyze the data by creating dotplots, stem graph for initial analysis to decide what´s next. If you ask me, the best reference I can give you about regression testing is taken the paper or similar you can get about descriptive analysis in statistic. Why? Because the important thing is the data you take into account. The only thing regression will say is if things that are trying to be related has sense or not. After that you have other tools to deep down into the analysis. Indeed, inside the deep down you can make the original regression testing deeper.

Thank you Sergio. The mention of descriptive analysis gave me some important keywords to help my research. As I'm sure you've encountered in large complex systems, the question of what is connected is not always an easy answer, and often relies on the expert knowledge of individual subsystems owners. What I'm considering at the technical integration level and project management level is how to put more structure behind the process. With many internal groups and external vendors involved, I will have to give some serious thought to how we might use data to help illustrate the connectivty.

You are welcome. In our case we are using simple regression. Just to put here source of information that have helped me a lot (I am using this from long time ago before things that R exists) take a look to Putman´s "Measures for Excellence" or Tom DeMarco "Controlling Software Projects". In fact, mainly the first one, is used outside software domain
