Agility in business means being able to quickly change goals and deliverables in the face of rapidly changing circumstances. An agile lean business case is one that changes often based on iterations of a process that assesses evidence of whether the goal is met. In practice this means doing the following:
• Keeping the business goal strategic in the face of market and other forces that impact the plan for its implementation.
• Ensure that facts are distinguished from hypotheses and that the riskiest assumptions are dealt with first.
• Implement small solutions and, where they are effective, focus more effort into them.
• Look at outcomes rather than delivery milestones: focusing on goals and outcomes will encourage responsiveness and adoption of new ideas for effective solutions.
• Adapt based on evidence: the business case should evolve and be refined based on a path to the customer’s requirements which is well-defined and any deviation avoided.
