A lot of this is, IMO, very basic - a project is not done until it’s tested and running in prod - I am surprised anywhere with engineers with any experience at all would act otherwise.<p>I don’t think having 40 people work on one thing at once is good at all. It’s like solving scaling by just getting a faster machine. Eventually you may not be able to purchase a machine fast enough to do everything you need to do… And you’re going to have a ton of deadweight.<p>I hate “agile” as practiced but, in theory, it solves this. If you scope out a project well, you should have a general sense for what cross-team dependencies exist and be able to put it on the other team’s plate. You need a decent amount of “trust” but ideally the other team will actually appropriately prioritize it, ie if it takes only two days of work to unblock a project with big business impact, they won’t push back that their Epic Rewrite v3 is too important and maybe they’ll get to it in 6 months.<p>The biggest problem I’ve seen is with bucketing all projects in long planning cycles (3 months, 6 months, 12 months, etc.). Every cross team dependency then takes about one planning cycle to be accomplished, and unexpected additional work/dependencies become nightmares. Also, while “ownership” and specialization are good to an extent, fixing a particular engineer to a specific domain over long intervals almost always causes problems because X% of engineers either aren’t skilled enough to be able to handle owning a domain, leave the team, get delayed, etc. If everybody is fully booked for a long time, there isn’t slack to help them, and it suddenly becomes a Big Deal to assign someone off a domain (because the person struggles for months and messes up a big project, rather than identifying they are messing up after weeks and course-correcting by putting them on something they can be more productive working on), and every project with more than a few people gets delayed because there’s no way to fix one or two engineers on the critical path dropping the ball.<p>What both this article and agile touch on is the benefit of having a flexible planning structure and not over-committing or trying to plan too far in advance. IMO, that is the key to getting shit done. I think you can do that without taking it to the extreme of having only one project in-flight though.
