Project sizing

Are you managing a small or large project? What difference does the size of the project make? One of the major differences between any two projects is the extent to which the key elements of a project management methodology are applied.

This Project Sizing Calculator provides a guide to some of the issues to consider when deciding on the extent to which you are going to use a methodology. There are many other factors that should be taken into account, such as the level or degree of risk, technology requirements, number of stakeholders, and the skill level of the project team.

The following criteria have been developed to assist in determining the size of projects undertaken within the Tasmanian Government.

Once you have completed all 9 questions, and clicked on the button 'Calculate Project Size', the calculator will determine if you have a Small, Medium or Large Project.

For further information on how much project management discipline should be applied, refer to the Project Sizing Fact Sheet. The approach in the Fact Sheet is not prescriptive.

After taking all factors into account, a rational decision has to be made on how to manage the project in the most suitable way. However, if your project is cross-Agency, whole-of-Government or involves more than one tier of Government, the application of project management methodology to its fullest extent should seriously be considered.


1. What is the size of the Project Team (FTEs)?
1- 2 people 2 - 5 people 5+ people

less than 6 months 6 - 12 months greater than 12 months
3. How much variation in the timeframe can be tolerated?
Schedule is flexible Schedule can undergo minor variations, but deadlines are firm Deadline is fixed and cannot be changed; schedule has no room for flexibility
4. How complex is the problem and/or solution? Is the solution difficult to achieve?
Easily understood, and solution is readily achievable Either: difficult to understand problem, solution is unclear; or solution is difficult to achieve Both problem and solution are difficult to define or understand
5. What is the level of strategic importance?
Affects core Agency service delivery and/or directly relates to key initiatives in the Agency Strategic Plan Some direct business impact and/or relates to a low priority initiative in the Agency's Strategic Plan Internal interest only
6. What is the political importance?
Major political implications Some political implications No political implications to either proceeding or not proceeding
7. What is the total project cost?
less than $25K $25K - $250K greater than $250K
8. What level of change will be implemented?
Impacts on whole-of-Agency, more than one Agency, whole-of-Government, or more than one tier of Government Impacts a number of business units Impacts a single business unit only
9. Are there any dependencies and/or inter-related projects?
No major dependencies and/or inter-related projects Some major dependencies and/or inter-related projects, but considered low risk Major high risk dependencies and/or inter-related projects

Please ensure that you have filled out all 9 questions before calculating the project size.

Calculated Result:
The project size is ...
