The Mythical Man-Month: Essays on Software Engineering is a book on software engineering and project management by Fred Brooks first published inwith subsequent editions in and Its central theme is that "adding manpower down syndrome essays a late software project makes it later. He had added more programmers to a project falling behind schedule, a decision that he would later conclude had, counter-intuitively, delayed the project even further, down syndrome essays.
He also made the mistake of asserting that one project—involved in writing an ALGOL compiler —would require six months, regardless of the down syndrome essays of workers involved it required longer. The tendency for managers to repeat such errors in project development led Brooks to quip that his book is called "The Bible of Software Engineering", because "everybody quotes it, some people read it, and a few people go by it".
The work was first published in ISBNreprinted with corrections inand republished in an anniversary edition with four extra chapters in ISBNincluding a reprint of the essay " No Silver Bullet " with commentary by down syndrome essays author.
Brooks discusses several causes of scheduling failures. The most enduring is his discussion of Brooks's law : Adding manpower to a late software project makes it later.
Man-month is a hypothetical unit of work representing the work done by one person in one month; Brooks's law says that the possibility of measuring useful work in man-months is a myth, and is hence the centerpiece of the book. 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 down syndrome essays the workers performing them.
Therefore, assigning more programmers to a project running behind schedule will make it even later. 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. 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.
Brooks added the chapter "No Silver Bullet—Essence and Accidents in Software Engineering" and further down syndrome essays on it in the chapter "'No Silver Bullet' Refined" to the anniversary edition of The Mythical Man-Month.
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. The argument relies on the distinction between accidental complexity and essential complexity, similar to the way Amdahl's law relies on the distinction between "parallelizable" and "strictly serial". The second-system effect proposes that, when an architect designs a second system, it is the most dangerous system they will ever design, because they will tend to incorporate all of the additions they originally did not add to the first system due to inherent time constraints.
Thus, down syndrome essays, when embarking on a second system, an engineer should be mindful that they are susceptible to over-engineering it. Take one down syndrome essays, patch it around. The author makes the observation that in a suitably complex system there is a certain irreducible number of errors. Any attempt to fix observed errors tends to result in the introduction of other errors.
Brooks wrote "Question: How does a large software project get to be one year late? Answer: One day at a time! Continued attention to meeting small individual milestones is required at each level of management.
To make a user-friendly system, the system must have conceptual integrity, which can only be achieved by separating architecture from implementation. A single chief architect or a small number of architectsacting on the user's behalf, decides what goes in the system and what stays out. 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.
A novel idea by someone may not be included if down syndrome essays does not fit seamlessly with the overall system design. In fact, to ensure a user-friendly system, a system may deliberately provide fewer features than it is capable of. The point being, if a system is too complicated to use, many features will go unused because no one has time to learn them. The chief architect produces a manual of system specifications. It should describe the external specifications of the system in detail, that is everything that the user sees.
The manual should be altered as feedback comes in from the implementation teams and the users. When designing a new kind of down syndrome essays, a down syndrome essays will design a throw-away system whether it intends to or not.
This system acts as a "pilot plan" that reveals techniques that will subsequently cause a complete redesign of the system. This second, smarter system should be the one delivered to the customer, since delivery of the pilot system would cause nothing but agony to the customer, and possibly ruin the system's reputation and maybe even the company.
Every project manager should create a small core set of formal documents defining the project objectives, down syndrome essays 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.
These documents may also reveal inconsistencies that are otherwise hard to see. 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 down syndrome essays to write as simple independent in-house programs.
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. 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.
The architect s are responsible for formulating a group picture of the project and communicating it to others. Much as a surgical team during surgery is led by one surgeon performing the most critical work, while directing the team to assist with less critical parts, down syndrome essays, it seems reasonable to have a "good" programmer develop critical system components while the rest of a team provides what is needed at the right time.
Additionally, Brooks muses that "good" programmers are generally five to ten times as productive as mediocre ones. Software is invisible. Therefore, many things only become apparent once a certain amount of work has been done on a new system, allowing a user to experience it, down syndrome essays. This experience will yield insights, which will change a user's needs or the perception of the user's needs.
The system should, therefore, be changed to fulfill the changed requirements of the user. This can only occur up to a certain point, otherwise the system may never be completed. At a certain date, no more changes should be allowed to the system and the code should be frozen.
All requests for changes should be delayed until the next version of the system. Instead of every programmer having their 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. a code generator tool that creates code based on a specification.
In addition, system-wide tools should be built by a common tools team, overseen by the project manager. From Wikipedia, down syndrome essays, the free encyclopedia.
