Large IT projects often fail due to lack of proper planning and execution. A survey found high correlation between lack of execution and dissatisfied shareholders. Key reasons for failure include lack of buy-in, unclear plans, and poor change management. However, following five steps can lead to success: establishing a steering committee of executive sponsors; forming a core project team of 4-6 members; setting up sub-teams with clear responsibilities; defining roles; and creating a one-page project timeline. These steps help overcome common issues and result in effective strategy execution.
