  • Defect Management Process reduces defects – Part 1

    Last month we talked about Root Cause Analysis and mentioned that the real benefit was derived when we stopped whole classes of defects in many places. However, that gain will not be realised without a Defect Management Process. Doing Root Cause Analysis without an attached process is a waste of time. It is like carrying out a Post Implementation Review or Lessons Learned and not acting on the results.

    As mentioned previously the root case analysis will tell you where the problem originated. In a project situation with a deadline looming we may need to fix that defect for the sake of delivering the project on time and with the required functionality. The Defect Management Process needs to keep that defect in a place where we can continue to act on it and fix the root cause not just the defect itself.

    Assuming that the defect has now been fixed, we can place it in a status where it is fixed (allows the project to proceed) but not fuly closed and filed away. At this stage, Quality Assurance can take over the defect and determine if there is a long term fix that can be implemented. It is quite possible that the fix will span multiple projects and applications. After all the root cause may be a process issue that is common to many projects.

    In a couple of weeks we will discuss how to implement that fix since it may not be project specific.

  • RCA – Why – Part 2

    Three weeks ago we asked why we would bother with Root Cause Analysis. We asked some questions and provided some answers. However that analysis concentrated on a single defect and the use of Root Cause Analysis in that case. The power of Root Cause Analysis really applies when we can solve a whole class of defects.

    There is a good chance that a problem that occurs in one place in the code has been repeated elsewhere. Errors have a tendency to be repeated! This came up recently when we were asked to look into a fix that had been implemented 20 years ago. It seemed to be unravelling. This is what is sometimes called a latent defect (one out in production code that suddenly appears). Suffice to say it was the same fix throughout the code and that Root Cause Analysis at the time it originally occurred would have been very helpful. It would have stopped the expensive and time consuming fix required recently. Root cause analysis would have paid for itself multiple times over.

    So the next time you have an error, take a look at it and see if you can put something down in the defect description indicating where it might have originated. Some classification will go a long way to describing where we need to concentrate more resources.

  • RCA – Why – Part 1

    Why bother with Root Cause Analysis on Defects? We have enough to do without adding to the work!

    1. We found a defect.
    2. We fixed the defect.
    3. We retested the defect.
    4. We closed the defect (pending success on item 3).
    5. Enough said. Let’s move on to something else!

    We acknowledge that once we have a defect, all of the above have to occur (hopefully only once and not repeatedly). But Root Cause Analysis is intended to prevent 1 – 5 ever coming back to bother us again. The key word is ever! We never want to see that defect again. In order to do that, we need to find out where it occurred, why it occurred; and make sure that combination never comes up again. In the long term this saves us a lot of money and time and allows us to concentrate on more important items.

  • Trend Analysis on Defects – Part 2

    Last week we discussed some prerequisites for Trend Analysis on defects. We are only discussing defects here but there are many other project metrics that could be analysed.

    Assuming that the prerequisites from the previous blog have been satisfied, what can we determine.

    1. The trend in the number of defects in each project (after normalization by some project size measurement).
    2. The trend in the number of defects in each Priority and Severity level (again after normalization).
    3. The phase or process that consistently generates the most defects.
    4. Any weak or defect prone supplier processes.
    5. Any product weaknesses that cause consistent customer complaints.

    Once we have the information listed above, we are in a strong position to fix any weak areas and correct any issues that may be costing us customers or internal funds. This is process improvement devoted to making sure that our internal processes are the best possible and we are generating the best possible product. There is more to trend analysis than we are mentioning here, but there are entire books and conferences devoted to this topic. We have only touched the surface of one item we can measure, address and improve.

  • Does your software Testing Pay – Part 4

    “Does your Software Testing Pay” is the question we posted six weeks ago. We posted a simple calculation for a ROI and then a few comments that were received as feedback. Those comments were appreciated since they extended the idea past the direct defect costing calculation. Today we want to wrap up this series with some general comments that extend the idea a little farther.

    For the most part we have concentrated on the Software Testing aspect of Quality Assurance. Almost everyone we speak with is familiar with this aspect. Most software companies or those who depend on software complete some form of testing and the concept of testing can be generalised to cover a multitude of activities. However, it is not the entire picture.

    So, at the risk of making the title slightly inaccurate, what other aspects of Quality Assurance can be considered:

    1. Process improvement for the entire SDLC.
    2. Timely intervention at the Root Cause of many of the defects to prevent them from occuring in the first place.
    3. Concentration on the required end-result to make sure everyone is working towards that end. It is suprising how often this is obscured in large organisations. We attended a course a couple of weeks ago and spoke to the instructor afterwards and apparently many people on the course have only been told a very small piece of what they need to do (and part of that was to attend the course although the reason why was not provided). Not only is that against the concepts of keeping people informed of why they are doing something but it is also very de-motivating.

    The above list (particularly number 1) can cover a lot items that are very detailed and can add a lot of value to the Quality Assurance efforts. We may take this up in the fall.
