Map roadmap dependencies
Which prerequisites can block the roadmap?
Direct answer
Each dependency links an upstream and downstream object to a type, date, owner, status and fallback option.
01Secure, decouple or rephase critical dependencies.
02The rule, the evidence and the next review date stay visible.
How to use this
Move from the question to the deliverable.
Which prerequisites can block the roadmap?
Secure, decouple or rephase critical dependencies.
Dependency map
Dataset · SQ-10
Turn a list of prerequisites into a governable set of dependencies
A useful dependency states its type, its required date, its owner, a fallback and the impact of a delay.
Illustrative data set for the launch of a new B2B offer.
- 01Identify
Name the upstream deliverable actually needed, not just the team concerned.
- 02Type
Distinguish finish-to-start, start-to-start, external constraint and resource availability.
- 03Quantify
Estimate the lead time, float, impact and decision deadline.
- 04Secure
Assign an owner and a fallback to the critical links.
Dependency register of the launch
The register shows that legal validation, despite its short duration, carries the greatest delay impact.
| Upstream | Downstream | Type | Required date | Owner | Fallback | Delay impact |
|---|---|---|---|---|---|---|
| Offer approval | Messaging | Finish → start | 12/09 | Product marketing | Restricted version | 4 d |
| Messaging | Creative | Finish → start | 18/09 | Brand | Minimal kit | 6 d |
| Pricing | Sales training | Finish → start | 20/09 | Finance | Provisional range | 3 d |
| Legal | Landing page | External constraint | 24/09 | Legal | Form without evidence | 8 d |
| Tracking | Media activation | Finish → start | 27/09 | Marketing ops | Pilot budget | 5 d |
| Creative | Media activation | Start → start | 25/09 | Acquisition | Static formats | 2 d |
01The Legal → landing page dependency must receive an escalation date before 24/09.
02The “pilot budget” fallback reduces the impact of a tracking delay, but limits the reading of performance.
03A dependency without a fallback must be visible in the risk register.
Fictitious data. Delay impacts must be recalculated from the real roadmap.
