Describe the six steps in a typical preliminary investigation. Why should an analyst be careful when using the word problem?

Program Plan Intro

Description of the six steps in a typical preliminary investigation and explanation of an analyst and the reason of using the word ‘problem’

Program Explanation

A preliminary investigation is a process where investigating staff examines the existing system and placed requirements for the new system. These analyses are documented and presented as and when asked for it. Basically, the system analyst conducts a preliminary investigation for studying the system's request and recommended action accordingly. After authorization, the analyst interacts with the manager, user and stack holders which are shown below in a pictorial format. This picture also states the six steps which are taking by the system analyst for preliminary investigation

During a preliminary investigation, a system analyst typically follows the six steps. These are given below:

Step 1: Understand the problem or opportunity.

Step 2: Define the project scope and constraints.

Step 3: Perform fact-finding.

Step 4: Study usability, cost-benefit, and scheduled data.

Step 5: Evaluate feasibility.

Step 6: Present recommendations to the management.

Step 1: Understand the problem or opportunity

In this step system analyst analyze the problem and tries to figure out the current state of the system. It also checks that there is any need for a new system or by doing a modification of the existing system will solve the problem. By changing the system, some people are getting affected. It also determines who is getting affected by the changing of the system.

Step 2: Define the project scope and constraints.

In this step, the project scope defines the specific, realistic and measurable and time-bound of the project. It determines every single specific characteristic of the project. So, it will be very easy for the analyst to find out if some errors have taken place in the project.

Step 3: Perform fact-finding.

When the new system or new thing is introduced in the project then the technique of collecting information for the new information system is known as the fact-finding technique...
