In today's times - the BA has come to become a person of great value to an organization, and who is a generalist capable of functioning competently in diverse roles. Typically, these people have a broad educational background and a diverse skill set with a wide range of work experience in different jobs and industries. In essence, they are able to visualize the "big picture" - that is - understand the business from different perspectives, as well as the technology side of what can be effectively used to improve the business.
The Business Analyst Skills in a broad perspective comprises of the person being a Business Planner, Systems Analyst, Project Manager, Subject Area Expert, Organization Analyst, Financial Analyst, Technology Architect, Data Analyst, Application Analyst, Application Designer, and Process Analyst.
As we drill down deeper into the specific roles of a BA and understand the essential skills required for each of the roles, it would give a clear picture.
The major roles of a BA, as defined by certification experts are:-
1. Define and Scope Business Areas
The BA must be sure that the project scope is clear and complete before the start of detailed requirements gathering. The BA may be given the scope pre-defined by the project sponsor or may be responsible for defining and documenting the scope as part of the requirements gathering task.
Defining and documenting the project scope requires the BA to understand why the project has been initiated, and the objectives of the project. An important contribution of the BA to the project is the analyzing of the business problem without "jumping" to a solution.
In addition, a complete project scope will name and define all the stakeholders that will be involved with the project, including people, systems, internal departments, and external organizations.
Other important components of the project scope documentation include the project viewpoint, project assumptions, and business risks. These components give the BA the information necessary to prioritize and focus the requirements gathering.
Finally the project scope should include a high-level description of the business processes. It may also include a list of items that specifically will not be included in the scope. This gives the entire project team a complete understanding of the work that the BA will be doing during the detailed requirements gathering phase.
One additional task required of the BA, is the creation of an organized system for maintaining project information. A glossary should be started along with a filing system for maintaining all of the information that will be gathered during the project.
Essential Skills Required:
1. Facilitation skills to bring multiple groups together to scope project and get consensus
2. Ability to document the project scope using business terminology
3. Project scope documentation techniques
2. Elicit Requirements
The most important task of a BA is to gather the detailed requirements that clearly and completely define the project. We use the word gather because the BA must be sure to ask the right questions of the right people to gather accurate requirements. Further, we use the word elicit, since the BA must be able to get people to say all that they have to and not leave anything as assumptions.
It is critical that the BA initially gathers Business Requirements and completely understand the business needs before defining a software solution.
The BA must assess the type of project, the people involved, and the volume of information required; and then determine how and where to find the requirements. BAs have a variety of techniques available to them including interviews, facilitated information gathering sessions, surveys, questionnaires, observation, and existing documentation from which to choose. In addition, the BA will often have many people with whom to talk and several existing automated systems about which to learn.
Gathering complete, detailed requirements is an iterative process that involves the BA asking questions, pondering answers, asking follow-up questions, and bringing divergent opinions to consensus. It also involves prioritizing the requirements to assure that the most critical issues are addressed by the project solution.
Essential Skills Required:
1. Asking the right questions
2. Active listening
3. Interviewing techniques
4. Facilitation techniques
5. Documentation
6. Ability to categorize requirements
3. Analyze and Document Requirements
Requirements are analyzed and documented using an iterative approach. As each of the requirements is documented, additional questions will arise requiring the analyst to probe deeper. There are many different approaches to documenting requirements. The BA is responsible for following their organization's standard documentation format or for creating their own. When developing a documentation format, the BA must consider the best format for communicating with the information technology team and the best format for communicating with the business area experts. Both groups must be able to read and review the document and clearly understand the requirements. Some requirements are more appropriately documented in textual descriptions, others in diagrams or graphical displays. The BA must also determine the appropriate level of detail for the documentation.
Ideally, the entire organization uses a consistent documentation format and approach. This makes the review process easier for people working on multiple projects. It also allows the organization to constantly improve the format as quality enhancements are discovered. The BA is often the person leading the development and maintaining the standard documentation format.
Typically there are many requirements. To organize them and make them easy to review, they are divided into categories or groupings. It may be good to categorize requirements into Business, Functional, and Technical.
Essential Skills Required:
1. Analysis Skills
2. Understand the system development methodology
3. Utilize modelling techniques
4. Categorization skills
5. Prototype user interfaces
6. Develop a textual template for requirements
4. Communicate Requirements
The BA should be the best communicator on the project team. The role is to act as a liaison between the business area experts and the technical team. This role requires the BA to "speak" both languages. The BA must also work very closely with the Project Manager to ensure that the project plan is adhered to and scope creeps / changes are approved and documented.
As the requirements documentation is being created, the BA will conduct informal and formal requirements reviews. These review sessions increase the quality of the document by finding missing or unclear requirements. It is important that the information is presented to the business and technical audiences in a manner that is most appropriate for their understanding. Summaries of the requirements or various graphical representations may be appropriate as part of the reviews. Understanding your audience is critical to the successful communication of the requirements.
Essential Skills Required:
1. Run effective meetings
2. Active listening skills
3. Precision questioning techniques
4. Conduct formal and informal presentations
5. Write clear emails, memos, and status reports
6. Conduct a comprehensive requirements review
7. Change management
8. Write review summaries
5. Identify Solution
The BA should work closely with the Business Area Experts to make a recommendation for a solution and work with the technical team to design it. This recommendation may include software changes to existing systems, new software, procedural or workflow changes, or some combination of the above. If software automation is part of the solution, the BA should assist with the screen design, report design, and all user interface issues by providing detailed functional requirements.
If a software package is going to be purchased, the BA works with the Business Area Experts, IT personnel, and the potential vendors to discuss the requirements and verify that the package selected will meet the needs. The BA may also be responsible for writing the Request for Proposal (RFP). Detailed business and functional requirements should be completed to accurately reflect the needs for the software and a thorough review should be conducted.
Essential Skills Required:
1. High level understanding of the software design
2. Ability to evaluate vendor software packages
3. Ability to estimate solution costs and benefits and build a business case for implementation
6.Verify Solution meets the Requirements
The BA should remain involved in the project even after the technical team takes over. The BA reviews the technical designs proposed by the design team for usability issues and to assure that the requirements are being satisfied. Once the solution is developed into software, the BA is uniquely qualified to assess the software and determine how well it meets the original project objectives.
The BA should work closely with the Quality Assurance team and to assist with the entire testing process. Testing is based on requirements, so the BA's intimate knowledge of the requirements allows accurate design of test cases. If there is no Quality Assurance team available, the BA can still assist with User Acceptance testing, the time when the Business Area Experts are asked to approve the software for implementation. As the software is tested, the BA ensures that it is clearly documented and reports defects and variances from requirements.
Essential Skills Required:
1. Basic understanding of system design concepts
2. Knowledge of software usability principles
3. Understanding of testing principles
4. Ability to write and review test cases
