Improving Your Test Process with TMMi Assessments

I was in a client call earlier in the week, discussing test process improvement, and they asked me what the most common improvement areas identified are. As an individual and as an organisation we have assessed hundreds of organisations so I think that I’m well qualified to comment based on our experience.

In this article I am going to discuss the three most common areas where we see room for improvement, as well as why they are important:

Risk management
Review Process
Metrics and KPIs

Risk Management

Firstly, and most obviously, risk identification, prioritisation and reporting. Testing is really nothing more than a risk mitigation exercise, so understanding what the risks inherent in your product are is vital to successful testing. We would always recommend gaining an understanding of the risks and planning and reporting on your testing accordingly.

If you don’t fully understand the risks there are a few pitfalls that you can fall into. Firstly, you may not adequately test against the most important risks, either because you didn’t identify them at all or because you didn’t prioritise them highly enough. This directly impacts on the effectiveness of your testing, raising the possibility of defects leaking into the production environment with all the cost and adverse impacts that can incur.

Conversely, a lack of understanding of risk can lead to over-testing. Extensive testing of areas that are very low risk may be a waste of time and will have a direct impact on the efficiency of your testing. Cost and speed to market are almost always important factors and any unnecessary testing can affect those.

Finally, when making the decision to release to production, it is important that the testing carried out gives the information required to make that a fully informed decision. If you’re not taking risk into account this just isn’t the case.

Many, many words have been written about risk and testing and there are many ways of assessing it, based on your organisation’s ways of working. There is no one-size-fits-all solution so we help with context-appropriate advice where we see potential gaps in the process.

Review Process

The second area I’d like to talk about is reviews, effectively the “testing” of requirements and other documentation. Having the techniques to adequately review the documentation that you are basing your testing on is vital to stopping defects at source – shifting defect detection left.

You need to be absolutely certain that the documents that you are basing your testing on (e.g. functional and technical designs, requirements, user stories etc..) don’t themselves contain errors, inconsistencies or ambiguities. If they do then the likelihood of defects being introduced during design and coding is vastly increased.
There are a number of types of review; distributed, walkthroughs and inspections for example that can be used and they often have increasing levels of formality and rigour. Having the right people carry out reviews is also key, as is ensuring that people aren’t wasting time reviewing details in documentation that they are not expected to understand – asking people with specific expertise to only review the sections of a document that are relevant to them is a more efficient way of carrying out reviews.

Recording outputs from reviews can be a useful way of spotting trends in documentation and making that documentation better and more usable.

We often observe that organisations don’t provide enough guidance on how reviews should be carried out (who should be involved and how, what type of review should be carried out, how observations should be recorded) and as a result defects that could have been identified much earlier make it through to later phases of testing, perhaps even into production, with all the additional cost that causes.

In short, an effective review process is one of the best means of shifting your test effort left and streamlining your route to production.

Metrics and KPIs

The third area I’d like to talk about is metrics, also known as Key Performance Indicators (KPIs). What do you measure? How? And, why?

There are a number of aspects of metrics that we observe and comment on. Firstly, “why”. Why are you measuring what you measure? What insight will each metric give you and how can you use it to improve your processes? Most organisations today are data rich, but unless you use that data to support your organisational aims, what is the point of it? We still see organisations collecting data “because they can” and producing enormous reports with dozens of data points that nobody ever reads. Pick metrics that are useful to your organisation and will be understood and, most importantly, acted upon by your audience.

It is important to understand that your metrics needs and capabilities may change over time as your process maturity changes. Ensuring that your metrics evolve as your processes mature is vital to maintaining their relevance and ability to support your goals.

Consistency of metrics gathering across your organisation is also key. We see programs or projects capturing different metrics or using different definitions of metrics (the criteria for something like “priority”, for example, need to be defined). What this can mean is that organisations aren’t comparing like with like when trying to make comparisons across projects and that any consolidated organisation-wide measures are flawed.

In short: more is not always better; ensure value is gained through relevance to your current state; be consistent in measurement and definitions.

Our intelligent Test Method (iTM) includes definitions of a number of suggested metrics. We work with our clients to identify and implement those relevant to them at that point in their process evolution and to potentially identify any more bespoke metrics that are right for them.
