Ramblings on Software Delivery February 28, 2016

I expect there will be a time in the not distant future where software development will be easier. So we are clear, I mean predictable, common even.

electrical outletWhile not fully equivalent, here is an highly simplified example.The electrical socket outlet is a common fixture found in commercial and residential buildings. This did not happen by accident. The generation of electrical power and subsequent demand caused a great deal of standards, regulation and common design elements.  They were required and fundamental to broad use of electrical and ubiquitous availability.

Software best practices constantly evolve and there have been lots of advances from the 1GL, 2GL and 3GL days. Yet, despite those improvements,  a recurring challenge on projects for me concerns the final product. By that, I mean delivery and all that goes with it. Not in any order, but these include customer acceptance, integration testing, launch, cut-over, final QA. From my experience, what should be common and predictable instead is anything but. Each project has unique challenges but the over all release process is the same.

And, yet. Here we are with 4 and 5GL programming and the fundamental challenges that remain to be solved. Code objects are inter operable; APIs are well understood but ad-hoc. Seems to me that there should be more common functions and libraries that provide a lot of the basics. And they do – to a point. But not at the same level as electrical outlet.

Perhaps the challenge is more with interfaces and data types (schemas). But I digress. Delivery and integration of software remains a crucial phase (see delivery above). Imagine a time when delivery is the same as generating power and connecting to the ‘grid’.  Delivery is then driven by demand and usage among other things. Yes, cloud computing comes to mind and that has made things easier.

Which leads me to release planning using Agile practices. A good step forward  toward common delivery. Getting more consistent release process is always preferred to ad-hoc. I have earlier posts about this topic and I expect there may be future ones as well. It is an evolving practice and gets better all the time.

ITIL outlines release management best practices. I know that the state of the art in software development will get to the electrical power example I mentioned earlier. The general consensus is we have achieved a basic process for delivery. Understanding current state, defined and consistent intervals,use standards and automate when and where ever possible are part of best practices.

What other challenges will remain going forward? How will standards be revised, improved to get to the electrical power equivalent state?
