If you’ve worked well in a corporate and business IT environment for further than year, either as a Business Analyst, a Developer, an Architect, in Quality Assurance, or in Application Support, you’re acquainted with the way the typical IT task will go probably. For example, let’s say you’ve been asked to lead a project which involves creating a system to control a mail-order DVD rental service (like Netflix).
The project may likely cover these basic steps:1. The Business Analyst works together with the Business Stakeholders (often referred to as IT’s clients) to assemble business requirements. 2. The Business Analyst then works together with a Systems Analyst or Architect to convert those business requirements into System Requirements. 3. THE MACHINE Requirements are then handed to something Architect who describes a “physical” design to put into action these System Requirements.
4. The Architect then works with the Developers and QA to ensure their physical design is being correctly implemented. 5. The Business Analyst performs User Acceptance Testing as approved by the initial Business Stakeholders to guarantee the requirements have been applied needlessly to say. 6. Once the stakeholders sign-off on the user approval tests, the operational system can be relocated into creation.

Of course there may be other necessary steps to check out. Availability testing, to ensure the system doesn’t have any one points of failing, and can meet its availability requirements. The final four factors, while necessary, are not of any interest outside of IT specifically. 5 at most once, only when the customer’s movie rental is received past the due date.
3: A Customer must not have significantly more than three (3) movies out for rent. 2 result in the client not having the ability to rent a movie of their choice? 1.00. How often is this guideline invoked then? 2, if the limit is changed by us of 3 movies to 2 movies, how often are customers endeavoring to exceed the limit, and is this impacting our bottom line?
To answer these questions, in all probability extensive changes would need to be made to the underlying system to explicitly log guideline behaviour, and following that generate custom reviews. 3 (where we’re changing the limit from 3 down to 2), we would also likely have to execute some heavy duty statistical analysis that may be beyond the purview of anyone working in the IT section.
