Business Analysts are traditionally the "change enablers" in a company, with their continuous focus on identifying improvement opportunities and recommending solutions. When it comes to business intelligent automation, they are in the best position to identify automation opportunities in the business processes and to accelerate the implementation by documenting the "as is" state, formulating the requirements for the automation solution, as well as testing the actual implementation.
First of all, Automation Business Analysts have to be Business Analysts. They need to know Business Analysis frameworks, domain analysis techniques, delivery frameworks such as Agile and Waterfall, elicitation methodologies, process mapping, and impact analysis. Business Analysts need to be competent in problem-solving and project management and be proficient with Excel. Automation business analysis is a skillset which comes on top of these core competencies.
