A travel-goods brief becomes more useful when it describes the sequence of access. Pick an occasion, then record the items and movements that matter.
For a short cross-city journey, access may matter more than maximum volume. A device, charger and personal essentials should be considered as a set. Decide what needs to be reachable while the main bay stays closed.
When the user moves between locations, the way the bag opens changes the space needed around it. Discuss whether the two halves should lie flat, whether the divider stays attached, and where contents move while the bag is upright.
Bulky, irregular contents make a different brief from folded clothing. Identify the largest object first, then review the mouth of the bag, strap attachment position and whether an internal base helps or obstructs the task.
RETAIL / PRIVATE-LABEL / COLLABORATIVE DEVELOPMENT
Own the use case, silhouette and design decisions. Mark the features that are essential and the choices still open.
Ask for the approved drawing, sample reference, cost basis and lead-time assumptions. Do not turn a concept page into a supplier commitment.
Agree measurable acceptance criteria, the test method and the sample condition. A pleasing image is not a result.

Add one access problem to the sample brief so the review has a clear purpose.
