Have you ever felt that you were given a situation that had unrealistic deadlines, a list of requirements with no end in sight, and you didn’t have even a fraction of the resources to complete what was asked of you? This is not an uncommon situation. With growing business requirements, increasing market demands, and a need to have things done “yesterday”, there has to be a way to protect teams from being asked to complete more work than what is realistically possible given the constraints of 24-hour days. Working with a team where these unrealistic requirements were given us, we found that we were able to protect the team by using the Scrum Framework. Scrum is an Agile framework for completing complex projects. Scrum originally was formalized for software development projects, but it works well for any complex, innovative scope of work.
