Planning Phase:
1. As an analyst what approach would you take in identifying business needs for an organization?
Answer)
As an analyst we have to understand the business needs for the organization by requirement analysis. There can be several approaches for identifying the business needs for an organization. We have to find the best possible scenario in which we can identify the business needs. One among the many most used types of identifying the business need by requirement analysis is the use of the Use-Case analysis. Use Case Analysis lets us see from the user's perspective and filter out important requirements and also changes needed in the old requirements. Use cases will be easy for the user to understand and relate. From the use cases thus formed, we will be able to get our final set of user/business requirements. Thus, this will be the suitable technique to collect requirements from the business.
2. What type of IT projects would make good use of your skills? Why?
Answers)
IT projects which are beginning to look forward to implement the system from the scratch and also the projects which are looking to upgrade from an old system to a newer system by implementing the business requirements, are suitable for the analyst skills where an analyst has to look for the business and customer requirements.
3. What advice would you give new analysts who are inexperienced and beginning the planning phase of a new project? Give at least two pointers and explain why you think it is important for a rookie analyst to know.
Answer)
There are certain advices that we would give to new analysts who are inexperienced and beginning the planning phase of a new project and why they are important to know:
a) Analysts should know which requirements gathering process to start with regards to the current system of the business and the application and business requirements. This is important as getting ahead with a unsuitable requirements gathering process is a problem for the analyst and the project and it would adversely impact the project.
b) Analysts should be able to finalize the requirements by analyzing the old system if any or through appropriate methods of new requirements gathering accurately in fixed time. This is important since the new analysts will take some time but the project cannot backlog because of the backlog in requirements gathering.
