Business Analysis is the activity of facilitating change in a company by defining needs and recommending value-adding solutions. Business Analysis projects can be different: strategic, tactical or operational. This means that business analysis can be used both within a project and in the further development of a company. Define the target situation and determine the task required to move from the current situation to the target situation. 

Business analysis on business value and ensures that it meets the needs and evaluates it after implementation. For this purpose, techniques and methods are applied that are assigned to the six knowledge areas of business analysis:

Business Analysis Planning and Monitoring

Elicitation and Collaboration

The business analyst is responsible for determining, organizing and analyzing information (from all possible sources, such as business and IT). The business analyst is responsible for ensuring that all stakeholders are understood and identified. Based on this, he participates with the stakeholders to design and deliver the appropriate solution. The role of Business Analyst (BA) acts as a bridge between business, operations, IT and all other stakeholders. This means that the BA is able to understand the different interests and translate them accordingly. The BA acts as a facilitator who ensures a common understanding. He is responsible for ensuring that. All these results in satisfied stakeholders. 

The core concept of business analysis identifies six core concepts that are interdependent: change, need, solution, stakeholders, benefit and context. A need is a problem that has been resolved. Changes can therefore trigger a need. A solution is a specific way to satisfy a need in a context. Stakeholders are individuals or groups who have a relationship to the solution. Benefit is the value for the stakeholder and it can be material (ie quantified eg monetary) or immaterial (ie qualitative eg reputation). If one of the core concepts changes, the other core concepts and their contribution to the benefit should be re-examined. If changes occur, the business analysis activities are often validated and, if necessary, the necessary actions are derived. In addition, the business analyst should always have the overall picture at least. Holistic and systemic thinking are of particular importance. 

Conclusion: Business analysis is both extremely relevant and challenging and requires expertise and experience.
