This frustrating trend starts with the title what the hell is a "man"-month. Whereas I have from time to time addressed that question in lectures, I have long wanted to essay it in writing. Take one down, patch it around. Besides these benefits, there is a lot of fun to be had because, inevitably, you will laugh knowingly as you remember a past project or your current one that has fallen into the exact pitfalls Brooks describes.
When n people have to communicate among themselves, as n increases, their output decreases and when it becomes negative the project is delayed further with every person added. Thus, when embarking on a second system, an engineer should be mindful that they are susceptible to over-engineering it.
Another technique Brooks mentions is not to develop software at all, but simply to buy it " off the shelf " when possible. Analyzing the software problem into the categories of essence and accident was inspired by Nancy Greenwood Brooks, who used such analysis in a paper on Suzuki violin pedagogy.
The book covers handling conflict, managing wildly differing personality types, infusing innovation into insane product schedules, and figuring out how to build a lasting and useful engineering culture.
Two persons' contributions should be especially cited: This can only occur up to a certain point, otherwise the system may never be completed. This system acts as a "pilot plan" that reveals techniques that will subsequently cause a complete redesign of the system.
The reader should be warned that the new opinions are not nearly so well informed by experience in the trenches as the original book was.
Let us turn to nature and study complexity in living things, instead of just the dead works of man. Anyone who has ever had to face the questions: It allows easy backtracking. This is because the time required for the new programmers to learn about the project and the increased communication overhead will consume an ever increasing quantity of the calendar time available.
I don't mean to sound like the grumpy reader mentioned in the epilogue, complaining that the book offered "nothing I didn't know already know" however experienced he might have been, I still doubt itbut whether from my limited experience in the industry first hand or second-hand through the various managers I've had over the years, the tenet that developers and time aren't interchangeable resources felt both familiar and self-evident.
We decided not to revise the original, but to reprint it untouched except for trivial corrections and to augment it with more current thoughts. An understanding of larger, non-technical issues can give you a strategic view to complement the tactical view so essential to design and construction job functions.
Another good book, Software Runaways by Robert Glass, is a good confirmation of that statement. This frustrating trend starts with the title what the hell is a "man"-month. Project estimation[ edit ] When estimating project times, it should be remembered that programming products which can be sold to paying customers and programming systems are both three times as hard to write as simple independent in-house programs.
Take one down, patch it around. Formal documents[ edit ] Every project manager should create a small core set of formal documents defining the project objectives, how they are to be achieved, who is going to achieve them, when they are going to be achieved, and how much they are going to cost.
The second-system effect[ edit ] Main article: Download Now Read hilarious stories with serious lessons that Michael Lopp extracts from his varied and sometimes bizarre experiences as a manager at Apple, Pinterest, Palantir, Netscape, Symantec, Slack, and Borland.
It should describe the external specifications of the system in detail, i. No Silver Bullet -- Essence and Accident. I find that teams can grow much more complex entities in four months than they can build.
A connection between good software design and Christian ideas of holiness pop up again and again, and they grate on me not just because they come across as a bit sanctimonious, but because oftentimes, the Christian lens actually distorts the content.
Brooks insists that there is no one silver bullet -- "there is no single development, in either technology or management technique, which by itself promises even one order of magnitude [tenfold] improvement within a decade in productivity, in reliability, in simplicity. No silver bullet[ edit ] Main article: In my opinion, the best developers are not those who have skills for coding novel and elegant solutions to difficult technical challenges though of course that's importantrather the best developers are those who also have a wider view of software development than just the code in front of them.
Wait, I just remembered - women DO come up. He writes, "I will contend that conceptual integrity is the most important consideration in system design. The architect or team of architects should develop an idea of what the system should do and make sure that this vision is understood by the rest of the team.

Therefore testing is usually the most mis-scheduled part of programming. For some years I have been successfully using the following rule of thumb for scheduling a software task: l/3 planning l/6 coding l/4 component test and early system test l/4 system test, all components in hand.
