Write an investment thesis
The investment thesis is the core of the Business Case: the problem worth solving, the outcome you expect, and the return you underwrite. This guide shows you how to capture it.
Before you start
Section titled “Before you start”- You need edit rights on the project — the Jira project lead or a nominated editor.
- While the business case is in Discovery (Exploring) or Draft, you can edit the thesis.
- Once submitted, approved, or in realisation, the thesis locks and becomes read-only corporate memory.
- Open the project’s Tollgate tab and select Business Case.
- Go to the Investment thesis section. The fields edit in place — there is no separate editor to open.
- Complete the core fields:
- Business problem — what’s wrong today, in the sponsor’s language.
- Outcome — what “done and worth it” looks like.
- Return expected — the payoff you underwrite, written as prose. Tollgate does not compute or score a return figure.
- Pick a Theme from the site’s curated list.
- In the Charter section, set the scope on both sides:
- Scope — in scope — what this investment will deliberately deliver.
- Scope — out of scope — the boundaries you deliberately exclude.
- (Optional, also in Charter) Add design principles — short decision heuristics the team commits to up front.
- In the Governance section, name the seats: Decision authority (sponsor), Project manager, and — where relevant — Customer representative and Supplier representative.
- Each section saves on its own — choose its Save button (Save investment thesis, Save charter, Save governance).
Themes group the investment on the Portfolio. If your project already has a custom Theme value, Tollgate preserves it. Design principles give a mid-project call something to decide by.
