Options consideredKnowledge Train is a PRINCE2 Agile Accredited Training Organization.
A business case should weigh up the competing options which have been considered. After all, there is usually more than one option. Perhaps an alternative option would have been for John to change his job to one nearer their current house. However, this wouldn’t solve the issue with the school.

For a project in an organisation, this is usually referred to as the operational costs of maintaining and operating the projects outputs e.g. an IT system. At this point, the couple knows the total costs over the timescales when the benefits shall be realized.
RisksKnowledge Train is a PRINCE2 Accredited Training Organization.
For any activity or project, it’s also important to understand the major risks involved. Risks are the uncertain things which may or may not happen during the period of the investment. There is only one risk identified here, which is the risk that the couple might lose touch with friends who live close to them right now.
