The objectives of this essay are to examine whether or not Brook?s original scepticism that ?no single new development in the next ten years would give software developers an order-of-magnitude improvement in productivity, reliability, or simplicity? and ??future progress depends upon addressing the data? are reversible. We will discuss Brook?s original thoughts and we will try to give alternative solutions (if any).
This essay, in general, accepts Brook?s thoughts as he worked on OS/360 one of the most known, for their size, software projects. Before we discuss what Fred Brooks is arguing, we ought to refer to the differences between software engineering and programming. These two concepts are, in fact, totally different. On one hand, programming is primarily a personal activity while on the other hand software engineering is essentially a team activity. In other words, a software engineering team, which is working on a project, may consist of many programmers. On the contrary, a programmer writes a complete program while a software engineer writes a software component that will be combined with components written by other software engineers to build a system. Furthermore, the component one writes may be modified by others in the software engineering team and it may also be used by others to build different versions of the system long after one has left the project. Finally, we must say that programming is just one aspect of software development. Most of the projects, including software projects, are usually running out of time, the budget limit is much higher than it was prearranged and also the delivered product is not remarkable.

For that reason, before a project is implemented its objectives, scope and deliverables should be addressed and defined. It is very important to have a clear understanding of what you are going to build and the most important thing is to build it on time. At this point it would be quite interesting to make a historical background. In the 1950s and early 1960s a program was considered to be satisfactory if it executed and if it was able to give an acceptable answer. We should always bear in mind that the amount of memory that was used by the computers did not give to people the opportunity to run large and complex programs. So, the key in writing a successful program had only to do with the skills of the programmer. As the years were going through, new memory technology was used which allowed larger programs to be executed. Thus, when people decided that the time has come to build complex programs only then they realise how difficult was to monitor large software projects. After this event it became quite clear that as the program size increased the probability of error increased even faster. So the problem of managing large software projects exists even in our days and we are unable to predict when it is going and if it is going to find a solution.
Software engineering technology was born when we realised that we were not capable of managing large software projects. This situation was referred to us, as ?software crisis? and it was characterised by many symptoms. The most visible symptoms of the software crisis have to do with late delivery of the product, over budget and also that product does not meet specified requirements. For all the above reasons, software engineering was seen as the cure to crisis resolution. Fred Brooks in his seminal paper, ?No Silver Bullet-Essence and Accident in Software Engineering?, is profoundly discouraging to those who are trying desperately to find an end to ?software crisis?. He argues that crisis is inevitable, arising from software?s ?essence? (the difficulties inherent the nature of the software) and not the ?accidental? (the difficulties that attend its production but are not inherent the nature of the software) that much. Brooks believes that the key to ?software crisis? is addressing the ?essence. His conclusion derives from considering “the inherent properties of this irreducible essence of modern software systems: complexity, conformity, changeability, and invisibility.” The idea is that if we can specify what is inherent the software process implementation then we will have a context within which to address the accidental problems that limit our productivity.

Software Piracy What is Software Piracy The PC industry is just over 20 years old. In those 20 years, both the quality and quantity of available software programs have increased dramatically. Although approximately 70% of the worldwide market is today supplied by developers in the United States, significant development work is occurring in scores of nations around the world. But in both the United ...
Software engineering’s emphasis on processes for fabricating software products, as distinct from emphasizing the products themselves, has clearly provided useful language and methodological improvements. But it has not provided, and seems increasingly unlikely to do so, a fundamental solution to the software crisis. Brooks made the same point when he argued that technology would not provide a silver bullet for the software crisis within the foreseeable future. Software is very difficult to produce for a lot of reasons. Firstly, software is an invisible medium and only when it is almost finished we can have a complete view of the delivered product. In other words, it is only towards the end that the developer and the customer are able to discover if the delivered product is satisfactory. The second reason is that software projects seem to be extremely difficult and complex to manage and construct. To be more specific, a software system consists of hundreds of procedures that are very difficult to monitor. The complexity of software is an ?essential? difficulty, which is very difficult to annihilate but we should, at least, try to limit. One way to limit the complexity of software is to have many people, with the same level of knowledge, working on the software construction.
The reason for having many people, with the same level of knowledge, working together is that you can minimise the gap between their thoughts. ?Changeability?, is another ?essential? difficulty that Brooks is referring to in his paper. To this difficulty it will not be wrong to add another one, which is ?the high cost of software? that is part of ?Changeability? and it will be explained later the reason for associating these two difficulties. First of all, we ought to say that hardware development is so fast that makes software development looking very slow. For this reason, software is very soon out of date. Furthermore, we have to decide whether we want to spend money on maintaining the existing software or building new one. Both decisions are quite dangerous and the biggest problem is that they both have a high cost. It is not an accident that most of the money spent on software involves the maintenance of it. Nevertheless, the problem is even bigger if we consider that the size of software systems being created has increased. This means that the cost for either updating or building new software will be quite high. As we have already mentioned before, ?essence? and ?accident? are the two properties that make the development of a software project so difficult.

Brookes believes that there is only one way to manage large software projects and that is to address the essence so, he believes is that ?no silver bullet is possible but several advances when working together will increase productivity greatly but there is no single development that will do it alone.? Brooke?s scepticism was based on the complexity and other inherent qualities of software, and on his perception that upcoming advances, such as object-oriented programming, time-sharing, automatic programming, graphical programming and artificial intelligence, would yield only marginal improvements. Moreover, Brooks allowed in his paper that a combination of more fundamental changes like buying ready made components in the newly developed mass market, rapid prototyping of applications, incremental development, and cultivating great software designers in programming organisations, could improve programming by an order of magnitude or more. Brooke?s fundamental changes have a lot of advantages. Firstly, we always have a working system even if it is limited or even if it is not exactly what we would like to have but of course it is better from nothing. Furthermore, code is being continually debugged to make sure that is running.

This acquisition has brought in a unique proposition wherein the company has to decide if it wants to consolidate the existing plants with the acquired plants or let them both run separately. This poses a unique administrative challenge to the president of the company. ...
Another advantage is that the problem area can be easily located as being probably in the segment just added. Last but not least important, this technique is applicable to large and small systems as well. Another point that was mentioned by Brookes to help the managing of large projects involves the need to have good program designers. Experienced are not always the most suitable designers for your project. So, we should always look for those programmers that correspond to the needs of the particular project that we are going to build. Brooks had his own experience on software projects as he worked on OS/360 one of the best known, for their size, software projects. This project was released with many errors, it was behind schedule, took more memory than it was planned, cost a lot more money than it was estimated and early releases were not working properly. Later on, the emergence of Software engineering changed the ratio of hardware and software costs and helped in maintenance of the software. Furthermore, advances in hardware (integrated circuits, magnetic disks, and microcomputers) have increased the demand for software. Advances in software techniques (multiprogramming and time-sharing) lead to more ways to use computers.
Brooks by using his own experience on large projects argues that the goals of Software engineering are: Firstly, to produce quality software, secondly with low cost and lastly to produce the deliver product on time. To sum up, we ought to accept that no silver bullet is possible to be found in the near future. Although, we should be hopeful that techniques for limiting this problem are possible to be discovered. One technique that is suggested by Brookes has to do with addressing the ?essence? but this is not the only one. Form what history has shown us up to now people learn from their mistakes, so it is possible that in a few years time other more effective techniques can be detected in order to manage large software projects. Basically, I believe that the gap between the hardware and the software progress is one of the biggest problems that we are up to. As the costs of storage and CPU cycles become insignificant relative to personnel costs, the hardware terms nearly drop out of the equation of trade-offs in software design. Thus, the human challenges of managing software’s complexity – presenting a coherent interface to the user, and co-ordinating the efforts of the development team – remain formidable for developers of today’s big systems.
