Estimating software like omelettes

If one of those women was already eight months pregnant, and those chances increase if you (randomly) take more women. Or have them steal a baby, at least one out of nine should be successful! If I wanted a baby, and I wanted it as fast as possible, I'd take as many women as I could get and not take any chances :D

All of that reasoning is actually another example of how software is in the state it is in now too. :laugh: Lead dev explains to PHB: "No, that's not really possible to build a nuclear submarine entirely from pasta." Less-experienced Dev comes along : "Oh, I can do that in Python for sure!!" :laugh:

No, no, no - that's not how Agile™ works. The chicken stops every six inches while it walks across the road (these are 'sprints'). It verifies with the stakeholder (aka the farmer) at each point that he's getting what he wants, i.e. the chicken across the road. The farmer can adjust the chicken's route any time he likes. Of course, none of the principals notice the traffic on the road...

Ok, that explains the chicken, but what about the pig? :) The Chicken and the Pig - Wikipedia[^]

And yet sales keeps telling the customers that the company has a golden goose. ;)

Gutless Estimating Observe that for the programmer, as for the chef, the urgency of the patron may govern the scheduled completion of the task, but it cannot govern the actual completion. An omelette, promised in two minutes, may appear to be progressing nicely. But when it has not set in two minutes, the customer has two choices --- wait or eat it raw. Software customers have had the same choices. The cook has another choice; he can turn up the heat. The result is often an omelette nothing can save --— burned in one part, raw in another. Now I do not think software managers have less inherent courage and firmness than chefs, nor than other engineering managers. But false scheduling to match the patron's desired date is much more common in our discipline than elsewhere in engineering. It is very difficult to make a vigorous, plausible, and job-risking defense of an estimate that is derived by no quantitative method, supported by little data, and certified chiefly by the hunches of the managers. Clearly two solutions are needed. We need to develop and publicize productivity figures, bug-incidence figures, estimating rules, and so on. The whole profession can only profit from sharing such data. Until estimating is on a sounder basis, individual managers will need to stiffen their backbones and defend their estimates with the assurance that their poor hunches are better than wish-derived estimates.

I keep having to tell my boss he can't schedule the release of work which isn't done yet.

Third choice, make a smaller omelette. If an omelette isn't ready in thirty seconds you're doing it wrong.

[COCOMO](https://en.wikipedia.org/wiki/COCOMO) (and COCOMO II) is probably the only significant work regarding software estimation either before or after Mythical Man Month. And, having used it, I'm not convinced that, because of the complexity of its model, its much better than a 'finger in the air' guess, especially for enw or novel software.

And like an omelette, you have to break a few eggs to get the job done. ;)

I am amazed no one mentioned project creep.... "Oh, can you add some mushrooms?", once you already folded the omelet.
A programmer, like a woman's work, is never done.

2 things: 1 - The more time spent getting a requirements document and initial design correct, the better the estimate. Too many weak managers (i.e. not leaders) push to get "something" instead of the right thing, and the team and customer pay for that later. 2 - If a manager cannot or will not stand up to the customer (internal or external) and push back in order to manage the software development life cycle correctly, then that person lacks the leadership, management, and sales skills necessary to do the job. An effective manager makes an understandable and convincing case for doing things the right way. In the end, customers want success, not headaches and broken promises. Managers that do their job because they read how in some book, learned in some course, or got certified in some methodology are likely to fail. All those sources of information are good, but if the manager cannot synthesize that information into their experience, insight, and intelligence to figure out how to best manage a given project, then that manager needs to step aside or be replaced.
