Better Business Cases™ Foundation and Practitioner: In-House Training Using this best-practice approach will allow organizations to reduce unnecessary spending and improve the decision-making process which gives you a greater chance of securing necessary funding and support for initiatives. The goal of the combined foundation and practitioner course is to develop a candidate's ability to deliver a comprehensive business case through encouraging expanded knowledge to guide the practical application of theoretical foundations. Upon the completion of this course, a candidate will be able to start applying the model to a real business case development project. The outline presented in the course overview will be addressed in the first 2 days, with the Foundation exam conducted on the morning of Day 3. Then the topics will be revisited at a deeper level, for 2 more days, with the Practitioner exam conducted on the afternoon of Day 5. What you will Learn At the end of this program, you will be able to: Develop the lifecycle of a business case and establish the relationships between the five cases Apply the steps in the business case development framework, in order to support the production of a business case, using the Five Case Model, for a given scenario.
