alt Hacker NewsI think you're confusing Deming with statistical process control.
It is true that SPC works best for the non-chaotic parts of product development and manufacturing alike. There are parts of product development that are non-chaotic, and SPC works just fine there, too.
In addition to SPC, Deming had strong opinions on how organisations ought to work and these are relevant also for product development. These are things like
- Understand the underlying customer need.
- The leaders shape the output of the organisation by shaping its processes.
- It is cheaper and faster to build quality and security into the product from the start instead of trying to put it in at the end.
- Close collaboration with suppliers can benefit both parties.
- Have leaders skilled in whatever their direct reports are doing. Use them as coaches normally and as spare workers in times of high demand.
- Collaborate across parts of the organisation instead of throwing things over walls.
- Don't just tell people to do better. Show them how they can do better. Give them the knowledge, tools, and authority they need to do better.
These are just as relevant for product development as for manufacturing. If anything, even more so, thanks to the chaotic nature of product development.

Not to detract from your main point, but being non-chaotic is still not enough for SPC to work. Almost all of development tasks have thick-tailed time distributions, even if one is perfectly capable of analyzing them, they are not controllable.

I think this is the biggest hurdle for US style management produced from the MBA cookie factories. Their only skill sets are MBA speak, assigning blame, taking credit and granting themselves the largest bonuses possible while telling all the actual workers generating value that "due to current financial conditions, your raise is limited to 2%"
