Key takeaways
From the reading, NOTE-835.
- Eight challenges (Table 1, p. 97). Disparity in work and benefit; critical mass and prisoner’s dilemma; disruption of social processes; exception handling; unobtrusive accessibility; difficulty of evaluation; failure of intuition; the adoption process.
- The disparity. “Groupware applications often require additional work from individuals who do not perceive a direct benefit”. Meeting schedulers need everyone’s calendar and help the convener; calendars were kept by managers, not by individual contributors, so the feature “is rarely used”.
- Not enough to remove it. “Even a net benefit with equal costs and benefits for all users will not guarantee groupware success”, because of critical mass and freeloading.
- An argument record refused. A management group dropped an issue-based system because “the explicit record of opposing positions that the application would immortalize was politically unacceptable” (p. 97). The case is unsourced.
- Email as the success. “The primary beneficiary typically does a little more work”: the sender types, the receiver reads at leisure.
- Advice. Add group features to applications already in use, provide direct benefits for all members, and beware applications that selectively benefit managers.
Standing in the record
Filed on 2026-10-06 at the owner’s request, with the rest of the design-rationale batch under ADR-030. Read on 2026-10-14 in NOTE-835, from the copy Microsoft Research posts on its site.
It is now the record’s read source for the disparity in work and benefit, which CLAIM-179 grounds in the unread 1988 paper (LIT-759). The disparity account is filed as THEORY-311, at the strength of an argued review. The reading qualifies CLAIM-179 twice: Grudin holds that removing the disparity does not guarantee use, and the one argument record in the article was abandoned for challenge 3, the politics of a permanent record of disagreement, not for challenge 1. It also states the disparity as one between roles at the same time, not between an author and a later reader, which is how the 2026-10-06 curation entry put it.
