The System Development is the interactive process which consists of the following stages
- Preliminary Investigation: One of the most tedious task is to recognize the real problem of the pre-installed system. The analysis has to spend hours and days for understanding the fault in the system. This fault could have however overcome if the Preliminary Investigation before installing the system was properly done. This is the first stage of the development of the system. In this stage the analyst makes a survey by gathering all the available information needed for the system elements and allocation of the requirements to the software.
- Analysis of the requirement: The analyst understands the nature of the information and the functions of the software which is required for the system. The analyst makes a brief survey of the requirements and tries to analyze the performance of the system which is to be developed. He also makes sure that he gets enough information and resources for building the appropriate system.
- System Design: The analyst actually makes number of designs of the system on paper or on the computer and sees to it that the rough image made of the system comprises of all the requirements or not. Once this is done, the analyst selects and finalizes a best suited design for the development of the system.
- System Coding: The analyst translates the code or the programs in such a way that they become in machine readable form. The coding step is very time consuming and involves number of rooms for errors.
- System Testing: Once the analyst is through with the coding stage he tests the systems and sees to it that it is working as per the expectations or not. He corrects the flaws in the system if any.
- System Implementation: This is one of the most vital phase as in this phase the analyst actually gives the system to the customer and expects for a positive feedback.
- System Maintenance: The last stage of the SDLC is that the analyst needs to maintain the system and see to it that it working within the standards set. He needs to maintain the system by removing the defects of flaws occured.
