SYSTEMS ANALYSIS

Systems Analysis is basically to determine the objectives and limits of the system under analysis to characterize their structure and function, mark guidelines to achieve the proposed objectives and assess their consequences. Depending on the objectives of the analysis, we find ourselves in two different problems:

• Analysis of an existing system to understand, improve, adjust and / or predict their behavior.
• Analysis as a prelude to designing a new system-product.
  

In any case, more formally, we can group tasks that make up the analysis in a series of steps that occur in an iterative way to validate the entire process: Conceptualization

consists in obtaining a very high level view of the system, identifying its basic elements and relations between them and with the environment.

Functional analysis

Describe the actions or changes taking place in the system. Such actions or conversions are specified as processes receiving inflows and outflows occur.

Analysis of conditions (or constraints)

should reflect all the limitations imposed on the system to restrict the scope of possible solutions. These times are referred to the objectives themselves System:

• Operating
  , such as physical constraints, environmental, maintenance, personnel, security, etc.
• quality and reliability, maintainability, security, coexistence, generality, etc..

However, in other cases the constraints are imposed by limitations on the different resources used:

• Economic, reflected in a budget Temporary
• , involving deadlines to meet
• Human
• Methodological, involving the use of techniques
• certain
  materials, such as space, tools available, etc..

Modelling

One of the most common and convenient ways to analyze a system is to build a prototype (a model in short) the same. Validation

analysis In order to verify that the analysis is right and avoid, if any, the possible spread of errors in the design phase, it is imperative to proceed with the validation. To this we must check the following points:

• The analysis should be consistent and complete
• If the analysis is presented as a preliminary step to make a design, we must also verify that the objectives are correct and feasible

A fundamental advantage of the construction of prototypes from the point of view of validation lies in These models, once built, can be evaluated directly by users or domain experts to validate the system on their analysis.
