Repairability Scoring Rubric v1.4
Here you'll find a summary of the various criteria considered when calculating iFixit repairability scores under scorecard version 1.4.
Scoring Factors
Weight | Note | |
---|---|---|
Design for Repair | 80% | Ease of disassembly/reassembly |
Service Manual (if any) | 10% | Free, public, available via OEM support site |
Parts Availability (if any) | 10% | Only OEM parts considered |
Unique Product Identifier | N/A | Gating function for full credit on service manual, parts availability |
Factors Not Considered
Parts Pairing | Where common repairs are inhibited by parts pairing or calibration issues (e.g. full or partial loss of function, authenticity warnings, etc.) for which the OEM provides no freely available software-based remedy, penalties are being developed for inclusion in a future version of the scoring model. |
Software Updates | Duration of software updates is slated for inclusion in a future version of the scorecard. |
Revisions from v1.3
Unique Product Identifier | Incorporated a gating function for full credit on documentation and parts availability criteria. Maximum points are reserved for devices which can be readily identified (model number, service tag, etc.) in a non-working state, making it straightforward to find compatible parts and instructions. |
Scoring Ranges | Refined scoring ranges for various device categories. |
Replacement Parts | Finalized and incorporated scoring for availability of replacement parts directly from the OEM (or from an endorsed third party, linked from the OEM's support website. |
Documentation | Refined the scoring calculation for documentation. Criteria for full credit include: repair documentation must be free and publicly available from the OEM support website (or linked therefrom); no registration requirement; presence of tools lists, parts lists with part numbers (or other means of checking compatibility), exploded diagram(s), troubleshooting procedures, schematics, and service procedures for all priority parts. |
