Here are two examples of project structures.
A company is organising an exhibition event. For this event, there are two main areas set up as projects, putting on the exhibition and advertising the event.
For the exhibition project, there are groups for expenditure and revenue. Expenditure includes items such as stand construction and venue hire, whilst the revenue group includes all the income such as exhibitor sales for the stands.
For the advertising project, there are also grouping levels for expenditure and revenue. Expenditure includes items such as designing the advertisement artwork and the printing costs of publishing the advert.
An accountant has a number of clients, and each client is recorded as a separate project. For each client (project), they have different job types, such as audit and return (tax return) which are set up as sub-projects. For each job type, they have particular groups, such as Audit 2005 or Return [Q2'05] which are set up as groups. For each group, they can record activities such as labour and expenses and bills as project items.
