Test Management is Wrong

Test Management is wrong. There. I said it.

I can't believe it took me this long to notice the obvious. If you are doing Software Development in any fashion, and are worried about how to manage your testing to develop a "quality" product, stop it.

Let's be clear about what I mean here. If you consider any software development life cycle (SDLC) process, you will find activities like the following arranged in some fashion or other:
  • Requirements gathering, specification
  • Software design
  • Implementation and Integration
  • Testing (or Validation)
  • Deployment
  • Lather, Rinse, Repeat (i.e. Maintain, Enhance, Fix, Mangle, Spin, and so on)

These activities aren't Waterfall or Agile or anything else, they are just activities. HOW you choose to do them will reflect your SDLC. I don't care about that right now. The part I'm picking on is the Testing bit near the middle, regardless of whether you do them in an agile, Waterfall, or some other way.

In particular, I am picking on the fallacy or myth that a good Test Management plan/process is what you need to develop and release a high Quality product.

Using MS Outlook to support SBTM

Okay, to recap, Session-Based Test Management (SBTM) is a test framework to help you manage and measure your Exploratory Testing (ET) effort. There are 4 basic elements that make this work: (1) Charter or mission (the purpose that drives the current testing effort), (2) Time-boxed periods (the 'sessions'), (3) Reviewable result, and (4) Debrief. There are many different ways that you might implement or apply these elements in your team or testing projects.

Let's take a look at tracking the testing effort from strictly a Project Management perspective. Years ago, when I first became a test manager, I was introduced to the idea of the 60% 'productive' work day as a factor to consider when estimating effort applied to project schedules. That is, in a typical 8-hour workday you don't really get 8 complete, full hours of work from someone. I don't believe it's mentally possible to get that. The brain needs a break, as does the body, and there are many natural distractions in the workplace (meetings, email, breaks, support calls, stability of the code or environments, and so on), so the reality is that the number of productive working hours for each employee is actually something less than the total number of hours they're physically present in the workplace.

That 'productivity' factor changes with each person, their role and responsibilities, the number of projects in the queue, and so on. Applying some statistical averaging to my past experiences, I find that 60% seems about right for a tester dedicated to a single project. I have worked with some teams that have been more productive and some much less.

So what does this look like? If we consider an 8-hour day, 60% is 4.8 hours. I'm going to toss in an extra 15 minute break or distraction and say that it works out to about 4.5 hours of productive work from a focussed employee in a typical 8-hour day. Again, it depends on the person and the tasks that they're performing, so this is just an averaging factor.
