By now you’ve no doubt realised that I’m a huge Deming fan. The man was incredibly smart, creative and clear-sighted. He was the King of Processes (“if you can’t describe what you’re doing as a process, you don’t know what you’re doing”), as well as a staunch advocate of the notion that “innovation comes from the producer – not the customer”.
Clause 8.3 is a neat intersection of these two observations by Deming. His work may be many decades old by now, but it has lost absolutely none of its power and relevancy. Keep his wisdom in mind as you work through this vital clause.
Look at the stages you use as well as the controls you have during and after those stages. Write them down on a whiteboard. Then check to see what controls you have in place to manage those processes – things like decision points, approvals, sign-offs, monitoring, meetings, customer review points etc. Put those on the whiteboard too.
The best way to determine this is to consider a list of 10 items, namely:
For example, here at Mango we use a range of processes with multiple stages that include activities like SCRUM and Agile development (these are two fantastic quality tools used by the software industry – if you’re in software and you’re not using them, get with the programme ASAP!). We also have continuous release processes where we update the product monthly.
It took us a few days to break down and describe the development process, but it was time well spent because it made things so much clearer for our whole team. Remember, as Deming pointed out, “it is not enough to do your best; you must know what to do, and then you do your best”.
Once again, the standard gives you a simple list of what you need to consider:
These include:
Once you have created your design (it could be drawings, specifications, coding, plans, models etc.), the standard (8.3.5) then requires you to ensure that:
At this point in working through the clause many people feel that the hard yards have been done, and spend little time or energy on the elements of review. Big mistake. Unintended consequences are always a possibility – not just for software, but for every single industry in existence – so to miss this step or to do a rushed job can be very expensive in terms of missed opportunities, and devastating with regard to costly errors.
Deming was very aware that everyone has blind spots – as he said, “the big problems are where people don’t realise they have one in the first place”. So take time to thoroughly review, authorise and check all changes to the design. You need to be sure that they don’t cause other issues (8.3.6). You want to ensure that you don’t have any blind spots.
Here at Mango, during each monthly release, we have a number of formal reviews to check on progress. In addition each requirement is designed, developed and verified by the Software Developer prior to delivery to a User Tester. The User Tester then validates that the requirement is working both prior, and after, release. Any problems are reported into the software developer for fixing. All changes are recorded, listed and monitored to ensure they are well managed.
