Facilitation Skills for Business Analysts: In-House Training This course is part of IIL's Business Analysis Certificate Program (BACP), a program designed to help prepare individuals pass the IIBA® Certification exam to become a Certified Business Analysis Professional (CBAP™). Business analysts are communicators who bridge the gap between people with business needs and knowledge and the people who will provide solutions. Business analysts are continuously involved in communications with stakeholders and developers as they create the solution to business problems. They participate in information-gathering sessions including interviewing, joint requirements definition, and Joint Application Design (JAD) workshops which are used to streamline information gathering and get immediate validation from user representatives. The business analyst is also involved with negotiating the solution with the stakeholders, upper-level management, and the developers, mediating among the groups when disagreements take place, and influencing the results of decisions during the solution cycle. This course teaches the methods needed to organize and run information-gathering events. It combines the basics of graphic decision making and modeling with facilitation, communication, and meeting management skills. What you will Learn At the end of this program, you will be able to: Identify the major touch points between key BABOK® Guide knowledge areas and business analysis communication Describe the facilitation skills that are most supportive of those intersections Improve your ability to apply these skills in the context of your business analyst functions Foundation Concepts The role of the Business analyst (BA) An Introduction to the BABOK® Guide Business analyst roles and the product / project life cycle (PLC) Facilitation skills for the business analyst The BABOK® Guide and Communication An introduction to the communication process Addressing basic communications challenges Planning business analysis communication Communication and BABOK® Guide tasks Targeted Elicitation Techniques Synergy between communication and targeted elicitation techniques Preparing for elicitation Cornerstone targeted technique: interviews Other targeted elicitation techniques Related general communication skills Group Elicitation Techniques Synergy between requirements communication and group elicitation techniques Cornerstone group elicitation technique - requirements workshops Other group elicitation techniques Related general communication skills - meeting management best practices Related general communication skills - facilitating best practices Process / Model-Based Elicitation Techniques Synergy between requirements communication and process / model-based elicitation techniques Process / model-based elicitation techniques Related interpersonal skills - problem solving and decision making Investigative Elicitation Techniques Synergy between requirements communication and investigative elicitation techniques Cornerstone investigative elicitation technique - document analysis Other investigative elicitation techniques Summary of elicitation techniques by usage in the requirements process Using Presentations, Structured Walkthroughs, and Influencing Structured walkthroughs, presentations, and influencing within BABOK® Guide tasks Cornerstone technique - structured walkthroughs General communication skill - presenting Related interpersonal skill - influencing Special Facilitation Skills - Negotiating and Mediating Negotiating Mediating
