IntroThe total or partial outsourcing of IT services is attrting more and more all types of panies. This model allows them to have the IT resources needed to develop their business without having to invest heavily in hardware and sofare infrastructure. Before outsourcing Lardarius Webb Ravens Jersey , the pany must reflect on what e expects from a partner. The pany must know precisely what is expected of outsourcing and what the return on investnt they can anticipate is.The analysis of the current situation and of the existing requirents, the specification of functional charteristics, and sotis the legal frawork are all aspects that must be mastered for a suessful project. A well-researched and defined requirents docunt is a prerequisite for any IT project.Hence the importance of making a clear and detailed requirents docunt with the supplier.It is essential to draw up a plete inventory of what will be outsourced and to clearly specify the requirents.What is a requirents docunt?The requirents docunt is a docunt expressing the need of the custor, the functions of the future sofare and the constraints to which it is subjected. Its main role is to define the needs of the custor and what will be the use of the final product. In addition, the requirents docunt is a tool which filitates the munication and information beeenthe client and the service provider.Why develop a requirents docunt?The requirents docunt has three different roles. First, it describes the service that is expected. It also contributes to defining the criteria used for selecting the provider.When an external provider is the supplier, the content of the requirents docunt is incorporated into the contrt. The mitnt to hieving the technical specifications, on schedule, bees thereby mandatory. Finally, the requirents docunt will form the frawork to monitor and assess the correlation beeen the perford tivities and the needs of the custor. The requirents docunt is an essential frawork to:• lay the foundation for the project's suess: a clear definition of needs, objectives, users, etc;• obtain a guideline for the project and reduce the risk of misunderstandings;• having a ans of validating the project step by step;• estimate the workload required for the project (rcial offers, budget and deadlines).Four objectives of requirents docunt:• Define the objectives to be hieved• Identify the mandatory constraints to be respected• Be a tool for dialogue beeen partners• Reduce the risk of error during the developnt and implentation stages.What it includes?The requirents docunt defines the functional scope of the application to be developed, that is to say, the full list of features and their description. There is no ready to use template. Its structure, aury and length depend on the size and purpose of the project. The idea is to get a basic structure which helps the provider understand “what is expected of him.Below you will find an example of a possible structure for a requirents docunt. The pliance with this structure is not mandatory, but the requirents docunt ould contain the following information:1. Introduction. The introduction presents the product to be made in terms of needs (what will it be used for) and briefly describes its main functions. This section also allows you to present any notations used in this docunt as well as the table of contents. 2. Equipnt. This section allows you to describe the physical resources used during the project (eg. so devices), as well as interfes.3.Conceptual model. The conceptual model provides an overview of the sofare to be created.4.Functional needs. Functional specifications describe the functions (or operations) that the sofare must perform. Eh function is described in detail, specifying its inputs and outputs.Here it is important not to forget 5. Non-functional requirents. Non-functional specifications are those requirents that do not refer to a function of the sofare. These specifications, expressing constraints, are basically of o types:• The constraints of the user interfe. We can distingui here the constraints imposed by the sofare environnt (eg, the web application must run under a certain application server, the user interfe ould run properly on a certain browser), by physical environnt (eg, the program must use the charteristics of a certain terminal) or the human environnt (eg, mands must satisfy a particular constraint);• performance constraints. There are, for example, constraints related to response ti, security constraints, etc.6. Subset and priorities for implentation. This section allows you to define any specific sofare versions, versions corresponding to subsets of the requirents described in paragraphs 3, 4 and 5. Sotis it may be useful to develop certain parts of the sofare first. This section provides, among other things, an order in the execution of tasks. 7. Maintenance information. It is possible that, once the sofare is running, so parts are more likely to change than others (evolution of the material, changing user needs etc.).Specifying this from the beginning in the requirents docunt may help to build the sofare in a way which filitates its developnt.8. Glossary. The glossary contains definitions of technical terms used in the requirents docunt. It ould assu no technical knowledge from the part of the client to whom the docunt is addressed.9. Index. The index must filitate the use of the requirents docunt. It is advisable to highlight graphically (eg by putting in bold) important references to a term, its definition by example.ConclusionA good requirents docunt is the reflection of understanding and mutual respect. The specification doesn’t have to dictate the provider how he ould carry out the project but it needs to describe .
