Constitute the first step in SDLC the overall information required by the system: identification, analysis, prioritization, and rearrange. In this stage there are some things that should be done, among them:
1. Identify potential projects. Potential and the project in question is how much profit who can be by, the duration of time available is insufficient to complete the project, and whether its resources are able to complete the project.
2. Classify and rank the project. If at the same time there are several projects that should be done at the same time it needs to be made classification and ranking of projects, and projects are most worthy to be done until the project is felt to be beneficial if done.
3. Selecting projects to be developed. If the classification and ranking has been established then the next step is to determine which projects should be done.
The resources involved are the users, systems analysts, and managers who coordinate the project. Activities are usually done at this stage include interviewing management of users, summarizes the knowledge gained, and estimate the scope of the project and documenting the results. This phase will produce a feasibility report contains the definition of the problem and summary of objectives and projects selected.

System Development Methodology
Some experts divide the system development process into a number of different sequences. But it will refer to the processes of the following standards:
1. Analysis
2. Design
3. Implementation
4. Maintenance
In its development, standardized processes were outlined in a method known as the Systems Development Life Cycle (SDLC) which is a common methodology in the development of systems that mark the progress of the analysis and design effort. SDLC phases include the following:
1. Project Identification and Selection
2. Project Initiation and Planning
3. Analysis
4. Design
6. Maintenance
1. Analysis
2. Design
3. Implementation

- logical design
- physical design

Understanding System Analysis and Design
System analysis is defined as how to understand and specify in detail what should be done by the system. While the system design is defined as explained in detail how the parts and information systems are implemented. Thus, the analysis and design of information systems (ANSI) can be defined as: complex organizational process in which computer-based information systems are implemented. Or it could be summarized as follows:
Analysis: defining the problem.
Second, the ANSI method is a method long used to build conventional software. Thus, the validity of standard measures that have been tested. This method has also been used extensively in various industries (technology that has been tested).
Third, ANSI offers a new profession as an analyst. In the previous section, we discussed that a responsible stakeholder in the implementation of all phases of the ANSI is an analyst. With the industrial development of the information system is the system analyst and a career in the IT world, offers a lot of fun and challenges, as well as the salaries are not low. And the demand for systems analysts and expertise year after year have also increased. Systems analyst is a challenging profession because it combines many skills such as analytical skills, technical, interpersonal, and managerial. This can be seen and responsibilities of an analyst is based on ANSI approach, which includes:
Analysis: defining the problem.
From requirements to specification.Design: solve the problem.
From specification to implementation.There is a key question, why the order of the stages in ANSI becomes very important. There are several specific reasons. First, the success of an information system depends on good analysis and design. Stages of the analysis will determine what should be problem solved on your organization. Errors in this phase will lead to the problem persists even though the information system has been implemented. While the design phase will determine what kind of system will function. Although at this stage of the analysis of the main problems has been mapped correctly, will result in failure of a design error problem solving by computer systems. Thus, these two steps is a crucial step for the development of the system.

- How to solve problems within the organization through information systems.
