> Imagine throwing out every process you just described (minimal specs and plans, no contracts, no documentation, avoiding as many processes and tools as possible), and instead replacing them with conversations. You'd have those conversations (dev to dev, dev to PM, PM to customer, dev to customer), spend a few days building software, and then have those conversations all over again, continuously looping until the product is either "done" or something more important came up to work on.
> Would you call that team "agile" or "waterfall"?
Waterfall, 100%. I've been through that hell - management comes down with a date and brief elevator pitch. Then we're in constant talks over the next two weeks to hit a date no one really understands the requirements or rationales of, ironing out responsibilities between teams without any holistic long-term architectural vision (because there isn't even a product vision).
> I'm not sure I know how to square "Working software over comprehensive documentation" with "well defined stories with great documentation" and "clean specs upfront".
Comprehensive documentation literally means a very high coverage, perhaps 100% coverage of architecture docs, tutorials, design specs, etc. I said "well defined" and "great" :)
Agile is not contrary to documentation. Instead, there is a recognition that documentation's value is the time saved on development/discussion. That balance point depends on the team, and should always be considered in retrospectives.
If you're a team of 3 that all know how everything works, without immediate growth prospects... yeah, who needs docs? On the other hand, a FAANG team of 12 growing to 30 over the next 3 months will need documentation.
My "right-level" of documentation is that a junior engineer can pick up a story and ship it alone. The story is not fully-defined - implementer will have to learn some things from the docs, read through some of the code, decide on implementation strategy themselves... but they should be able to do so without meeting with others.
Meetings are expensive for teams, and context switching is expensive for ICs. Meetings that require bringing in senior engineers[1] for story-level details is all but an organizational anti-pattern.
[1] Generally, I'd regard having any single SME in the critical path of implementation is an antipattern (borrowing from kanban, this person invariably becomes a bottleneck on a large fast-paced team)
- TameAntelope 5y agoSo you understand that you're taking a literal primary tenet of agile and calling it "waterfall", yeah? "Working software over comprehensive documentation" is one of only 4 values of the Agile Manifesto, and it's in direct conflict with what you're calling Agile.
- losteric 5y agoI feel like you're spouting Agile (TM) rather than https://en.wikipedia.org/wiki/Agile_software_development https://en.wikipedia.org/wiki/Agile_software_development - Agile is not one thing, it's certainly not a checklist. There are general philosophies of software development. The core is really adaptive planning and acceptance/flexibility to uncertainty, biasing towards shipping first. There is no requirement to be spending all day in endless meetings, nor an opposition to documentation. If more documentation increases velocity, why would that be anti-agile? More importantly, what works for you does not discredit another team's agile approach. I lead large and growing teams rapidly releasing greenfield software. We are definitively agile, and documentation is empirically key to that process. Perhaps your experience differs. I don't discredit that, merely provide my experience in contrast.
- TameAntelope 5y agoHm, what is your opinion of the Agile Manifesto?
- salawat 5y agoI'll second the concerns at touting FrAgile (TM). Too many teams woefully underestimate the level of work yhat goes into maintaining the full delivery of product, and the fact that as you scale up, process has to be in place to keep people working independently without running into issues. Waterfall's issue was that it stipulated there shalt be process from stage 1 before anyone even understands WTF anyone is doing. FrAgile(TM) is notorious for just cutting people loose and winging it, with no regard to system design, architecture and maintaining a cohesive whole over the entire process that keeps your business functioning. You can't just NOT make SOP's you can't have an onboarding process that can't ne negotiated by the average person. Doing so is a recipe for burnout/churnout and failure.
- TameAntelope 5y agoSo when you see, "Individuals and interactions over processes and tools." and, "Working software over comprehensive documentation." how do you square that with, "You can't just NOT make SOP's"?
