Design Review for Hardware

(before CDR)

V0.1

Definition

The objectives of the Design Review for Hardware held before the project CDR are as follows:

Review and validate the detailed design of the H/W (boards + mechanical) from technical standpoint
Ensure that the detailed design of H/W meets all project requirements (incl. Marketing, Service, Manufacturing and Material)
Clearly identify the risks related to H/W and possible contingencies
Review status of ASICs and S/W work to ensure good co-ordination with H/W
Perform last sanity check on refined plans (schedule and resources) for H/W implementation work to be conducted during Implementation Stage

Questions

Technical assessment

Does the detailed design of H/W meet the product specifications?
Are the technical options/methods proposed for H/W appropriate for the project (implementation plans)?
Is the choice of components (technology, type, characteristics, cost, availability) appropriate?
Have the key risks related to H/W been correctly identified and evaluated?
Are there any risks for H/W due to the status of ASICs design?
Are there any risks for H/W due to the status of S/W design?
What contingencies can we propose against those risks (eg type of simulations, # of revisions, schedule)?
Are the R&D test programs for H/W (Unit, Integration) appropriate?
What are the open issues which need to be addressed regarding H/W?

Cross-functional check

Does the H/W design support the Marketing requirements?
Does the H/W design support the Serviceability requirements?
Does the H/W design support the Manufacturing requirements?
Does the H/W design support the Manufacturing Test requirements?
Are there any BOM issues from the commodity/components engineers standpoint?
Have the Quality Control issues been addressed?

H/W schedule and resources

Is the proposed schedule for H/W implementation work appropriate?
Are the corresponding resources appropriate (# of people, type of skills)?
Have we identified additional H/W risks (technical, cost, schedule basis)?
From a H/W standpoint, are we ready to proceed to the Implementation stage?
