What are the Details of the Systems Development

The systems development finds its base in some of the concepts that can be summarized as the follows
1. Systems Analysis
a. Can be defined as the analysis of the various problems that an organization will try to solve mainly with the help of the information systems.
b. Involves the designing and the installing of the system.
c. Helps a lot in having an in depth understanding of the various business activities.
d. Involves division of the whole into parts for a better understanding.
e. Helps in analyzing the different types of the problems being faced by the company.
f. Helps in the identification of the user requirements from the proposed system.
g. Helps in getting to the solutions for the various problems being faced by the organization.
h. Helps in the investigation, the designing, the implementation and the evaluation of the information systems in an organization.
i. One gets a better understanding of the nature, the functions and the relationship of the various parts within the system.
j. Helps in the achievement of the integration of the organizational subsystems.
k. Plays a very keen role in over–coming the problems of the hierarchical organizational structures.

2. System Design
a. Tells how the system will fulfill the various required goals.
b. Specifies the data element.
c. Specifies the records and the files.
d. Develops the system.
e. Specifies the input Performa.
f. Specifies the data preparation formats.
g. Specifies the system output.
h. Develops the data flowchart.
i. Develops the feedback.
j. Develops the control mechanism.
k. Develops the programspecification.
l. Develops the operation specifications.
m. Identifies the personnel, who will complete these activities.
n. Helps a great deal in the planning of the resources.
o. Helps in scheduling, which at different times include the following

I. Switching over to the new system.
II. Training the user.
III. Carrying on the parallel operation.
IV. Completely reviewing the whole system.

A system design is said to be a good one only if it possesses the following characteristics
1. Acceptability
2. Flexibility
3. Economy
4. Decision facilitating ability
5. Reliability
6. Simplicity

3. System Implementation
a. Includes the various activities linked to the testing, the conversion and the handling over the system to the production.
b. Ensures and provides the maintenance and the modification as well.
