Ease of use, then, dictates unity of design, conceptual integrity. Also his point about end users influenced my thinking, he says that point of programming is not to make a program that can do something or other but to satisfy the user view spoiler [ or the purchaser, not necessarily the same person hide spoiler ] which for me was quite a paradigm shift from providing a definable technical service, to customer satisfaction and indeed one can nuance that particularly if thinking about public services were you have multiple parties expecting different outputs of a services.
Adding manpower to a late software project makes it later. The essays in The Mythical Man-Month cover a variety of topics, from management-related topics such as estimating and process, to lower level design and construction topics. Communication[ edit ] To avoid disaster, all the teams working on a project should remain in contact with each other in as many ways as possible—e-mail, phone, meetings, memos etc.
Yet I found this book very exciting the first time round and not just on account of the picture of prehistoric mega fauna caught in a tarpit view spoiler [ although the influence of that on my imaginative understanding of project work ought not to be underestimated hide spoiler ]. Even if in your current job function you do not have control over 20th anniversary edition engineering essay man month mythical software things as requirements, scheduling, and staffing, you are still directly affected by these realities, and a deeper understanding of their dynamics is beneficial for at least three reasons: To a working developer, it may not seem like such theory-oriented topics would be of much interest.
All requests for changes should be delayed until the next version of the system. 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.
It should describe the external specifications of the system in detail, i. On software his championing of the thrice noble microfiche may be too quaint for contemporary taste, and generally for all readers, all workers in this book and all presumed workers, united, all round the world, are men, which for somebody who was working not just in the 50s but into the 70s and 80s, strikes me as interestingly thoughtless.
The tendency towards irreducible number of errors[ edit ] 99 little bugs in the code. All of the preceding is a long-winded way of saying this: The manual should be altered as feedback comes in from the implementation teams and the users. That is why you will find that many of the books reviewed on the developer.
A novel idea by someone may not be included if it does not fit seamlessly with the overall system design. How does a large software project get to be one year late? The manual[ edit ] The chief architect produces a manual of system specifications. 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.
Software customers have had the same choices. Instead of assuming something, implementers should ask the architect s to clarify their intent on a feature they are implementing, before proceeding with an assumption that might very well be completely incorrect. So possibly I can not in fairness recommend this book widely, the fruits I plucked from it may not appeal to the tastes of others, indeed you may not find anything new or tasty there particularly if you are a thoughtful anthropologist of the workplace.
In addition, system-wide tools should be built by a common tools team, overseen by the project manager. The point being, if a system is too complicated to use, many features will go unused because no one has time to learn them.
He writes, "I will contend that conceptual integrity is the most important consideration in system design. This system acts as a "pilot plan" that reveals techniques that will subsequently cause a complete redesign of the system.
The book wraps up with "The Mythical Man-Month after 20 Years," written inwhen this edition was published. Specialized tools[ edit ] Instead of every programmer having his own special set of tools, each team should have a designated tool-maker who may create tools that are highly customized for the job that team is doing, e.
Brooks never bogs down into the boring mechanics of the aforementioned subjects. Every part must even use the same techniques in syntax and analogous notions in semantics. Thus, when embarking on a second system, an engineer should be mindful that they are susceptible to over-engineering it.
Unfortunately, the more purely technical essays, such as "Sharp Tools," have not fared so well, but these make up only a small part of the book.
Every part must reflect the same philosophies and the same balancing of desiderata. 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.
Implementers may be hired only after the architecture of the system has been completed a step that may take several months, during which time prematurely hired implementers may have nothing to do. 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.
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. Complex programming projects cannot be perfectly partitioned into discrete tasks that can be worked on without communication between the workers and without establishing a set of complex interrelationships between tasks and the workers performing them.
In the high-pressure worlds of software development for business and government, the biggest challenges to building great software are not technical challenges. At a certain date, no more changes should be allowed to the system and the code should be frozen. Any attempt to fix observed errors tends to result in the introduction of other errors.Few books on software project management have been as influential and timeless as The Mythical Man-Month.
