The Agile Arrow is a visual framework for managing complex sales deals, applying popular project management principles to sales work. It helps prioritize individuals, work, and outcomes that will make or break the deal, enabling salespeople to navigate complex deals with visibility into their progress. The framework emerged from a personal experience with a $250k renewal, where it helped turn around a deal by simplifying communication, visualizing milestones, and identifying stakeholders' roles and priorities. By embracing agile values and principles, such as simplicity, customer collaboration, and responding to change, salespeople can effectively manage complex deals and close them successfully.
