How To Estimate Software

Tuesday, October 12th, 2010

James Iry explains how to estimate software:

I haven’t looked at the problem.
Completed: 0%
Time estimate: about 2 weeks.

I’ve looked at the problem.
Completed: 50%
Time estimate: about 2 more weeks.

I’ve implemented almost everything. All that remains is the difficult stuff that I don’t really know how to do.
Completed: 90%
Time estimate: about 2 more weeks.

I’ve done everything. All that remains is documentation, code review, tests and error handling.
Completed: 99%
Time estimate: about 2 more weeks.

I still haven’t finished documentation, code review, tests, or error handling. The truth is I’ve been gold plating what I already wrote. But I just saw another problem that seems more interesting.
Completed: 100%
Time estimate: 0 more weeks.

And that explains the state of software security…

Lu An Li: For McChuck and thank you. Makes sense. Unity of command.
McChuck: Just as there can only be one king, and army may only have a single commander. Command, by its very nature, rests upon a single head. Two commanders will constantly butt heads, confusing the troops and adding to the natural chaos of war. They often end up fighting each other more than the enemy. Even if they have the best of intentions, two commanders will inadvertently misdirect each others’ troops and interfere with each others’ plans.
lucklucky: Maybe bad translation. But i think it means it is better to have 1 good and 1 bad than 2 good to be able to choose.
Lu An Li: “I believe it would be better to have one bad general than to have two good ones.” Someone explain this to me.
Gaikokumaniakku: After the lemur bites the millipede, it sprays its toxic secretion, which the lemur then rubs all over its fur. Research suggests that there is a practical purpose to this: the benzoquinone secretion functions as a natural pesticide and wards off malaria-carrying mosquitos. The secretion also acts as a narcotic, which causes the lemur to salivate profusely and enter a state of intoxication.
Freddo: If you want to reach the mass market you need an equally sized megaphone (or a lot of luck). A push by Oprah will do it, Joe Rogan probably to a lesser extend. Amazons algorithm and star rating have been wokified to the point of uselessness; goodreads fast approaching the same point. Aspiring writers get the advice to build their own internet presence, but that of course is a lot of work by itself. I like the concept of a book bomb where a group of like-minded authors do a push of a new novel.
Felix: And, no mention of romance novels. Aren’t they supposed to be 50% or better of books sold? Sure, there are big name romance writers. A lot of them, if the grocery store is indicative. But. No mention?
Felix: Jim, what are the important, unread books you have in mind?
Albion: As someone who has published a couple of books (independently) on-line I can testify no one reads them much. In a way not a problem as it was more of a hobby, and there is a certain pleasure in getting words down in roughly the right order. But in terms of return for effort, it is barely a penny an hour in all likelihood. As they say, don’t give up the day job. Equally I can go to a library or bookshop, and while there tens of thousands of books available, I know I don’t want to read...
Phileas_Frogg: Jim, Your comment is obviously true, and yet the religion of those Ellis Islanders has managed to intellectually persevere, and indeed dominate, in intellectually rigorous fields, and in particular at the most intellectually rarified branch of the government (SCOTUS is 6 Catholics, 2 Protestants, 1 Jew). It is an odd paradox. I suspect we’re seeing a selection process take place where the less intelligent, curious, and literate Catholics are ending up non-Catholic, while the more...
Jim: Pre-World Wars America was so much more literate than now that it may as well have been another planet. Nor has the displacement of Americans by the descendants of Ellis Islanders helped much.
Jim: No one buys books because no one reads books. There are books of great importance that practically no one has had access to for dozens or hundreds of years now available for free on the Internet Archive, and they have been “viewed” only a handful of times, let alone read. It would be comical were it not so tragic.
David Foster: Does this include books sold for Kindle and other e-readers? Sounds like it doesn’t. Also, I wonder how much more effectively books could be marketed by people outside the publishing establishment.
Phileas Frogg: And yet they continue to furiously, and quietly, ban or hide titles that they consider dangerous as rapidly as ever. Just ask Aleksandr Dugin, Harold Saltzman, or Jean Raspail. Odd.
Bob Sykes: One has to wonder what the aerodynamics of the huge WW II bomber formations were. Often hundreds of large aircraft flew in tight formations. PS. “Twelve O’Clock High” is still one of the best war films ever made.
Bruce: Begun, the drone wars have. Small drones are cheap and effective. Big drones, airplanes, and any static target you can Google is vulnerable. In ‘General Kenney Reports’, Kenney’s memoir of the Pacific War, he mentions Lindberg showing up quasi-illegally. Kenney put the man who babied a single-engine plane across the Atlantic in charge of training P-38 pilots to baby their fuel use, and P-38 ranges doubled.
Bob Sykes: Which is why Russia, China, Iran and North Korea have hypersonic missiles, and we don’t. Not even one successful test. Kunstler is pessimistic: https://kunstler.com/clu sterfuck-nation/pep-talk -on-a-dark-day/#more-216 11′
Gaikokumaniakku: “It’s unusual.” One might say it’s “unwonted.”
Dan Kurt: Re: “Selcouth” is not a word you see every day. It’s unusual. Ok. Strike selcouth and substitute eldritch.
Isegoria: “Selcouth” is not a word you see every day. It’s unusual.
