There are two parts to being in business, doing the work and managing the business. Usually driven by business rules, it involves a lot of operational analysis and flow charting, and the more sophisticated offerings in the space include not only process designers, but also simulation tools so processes can be run virtually to identify bottlenecks or other issues related to either people or underlying infrastructure.
As business analysts, we identify and define the solutions that will maximize the value delivered by an organization to its stakeholders. Business plans for startups are often shared with funding agencies, potential investors and venture capitalists to obtain the necessary funding. This will give you the discipline to devote the correct amount of time and energy in managing your business. Test cases should map back to the Business and System Requirements, and at the very minimum there should be one test for each requirement. Business anthropologists can also facilitate organizational restructuring for greater economy and efficiency.
The Business Analyst should be insuring that all identified changes to requirements get the appropriate management and customer approval and are then documented clearly (be sure to include the date the change was made and the reason.) Failing to manage requirements throughout the project will likely lead to confusion and frustration with both the development team and the customer.
Job titles for business analysis practitioners include not only business analyst, but also business systems analyst, systems analyst, requirements engineer, process analyst, product manager, product owner, enterprise analyst, business architect, management consultant, business intelligence analyst, data scientist, and more.
Not putting enough detail in the requirement: There is a tendency by the Development Team (especially management) to want to leave out detail so that there is more room for design changes. The analysis showed that small and medium companies in America that used business aviation consistently outperformed nonusers.
