Roles and Permissions
A role groups responsibilities, while permissions state the specific actions and resources available to an identity. Start from the least access each role needs and define exceptions explicitly.
What You Will Be Able to Decide
- Explain roles and permissions in product and business terms.
- Apply this decision: Start from the least access each role needs and define exceptions explicitly.
- Recognise this material risk: broad convenience roles silently give staff or customers access beyond their responsibilities.
- Ask a consultant for evidence rather than reassurance.
A founder is reviewing how the product will enforce rules and respond when a request does not go to plan.
A role groups responsibilities, while permissions state the specific actions and resources available to an identity.
A consultant can recommend and implement the technical approach. The founder still needs to decide which outcome matters, which risk is acceptable, and what evidence is sufficient.
The Founder Situation
A founder is reviewing how the product will enforce rules and respond when a request does not go to plan.
The immediate question is roles and permissions. The technical label matters only because it changes a product decision, a responsibility, or the evidence required before launch.
Technical term
Roles and Permissions
A role groups responsibilities, while permissions state the specific actions and resources available to an identity.
Treat it like a clause in a commercial agreement: its value comes from making expectations and consequences clear, not from sounding formal.
What Matters in Practice
Start with the product consequence, then choose the simplest technical treatment that protects it. A longer tool list is not a stronger plan.
For this decision, the useful standard is that important rules hold for valid, invalid, repeated, and unauthorised requests.
- Make the decision explicit: Start from the least access each role needs and define exceptions explicitly.
- Ask what evidence would show that the chosen approach works.
- Name the person or provider responsible when the approach fails.
- Record the result in the backend proposal and operational acceptance criteria.
A Proportionate Decision
Start from the least access each role needs and define exceptions explicitly.
The principal risk is that broad convenience roles silently give staff or customers access beyond their responsibilities. This does not require the most expensive possible solution. It requires the consequence to be understood and the control to match it.
- Describe the user or business outcome that must be protected.
- Identify the most credible failure and its consequence.
- Compare the simplest adequate approach with one realistic alternative.
- Set a review point for when the decision may need to change.
Strong Evidence and Weak Reassurance
Warning Signs
- Nobody can explain how roles and permissions changes a user or business outcome.
- The proposal does not address this risk: broad convenience roles silently give staff or customers access beyond their responsibilities.
- The only evidence is a successful demonstration of the easiest path.
- The decision has no named owner, boundary, or review point.
- A provider-specific feature is being mistaken for a permanent product requirement.
Questions to Ask a Consultant
- What decision are we making about roles and permissions?
- Which user or business outcome does the recommendation protect?
- How have we reduced or accepted this risk: broad convenience roles silently give staff or customers access beyond their responsibilities.
- What evidence can I review without relying on the original implementer?
- What is deliberately deferred, and when will it be reconsidered?
- Who owns the accounts, data, documentation, and recovery process?
Key takeaway
Key Takeaway
A role groups responsibilities, while permissions state the specific actions and resources available to an identity. The founder's job is to make the consequence explicit; the consultant's job is to recommend and demonstrate a proportionate implementation.
