24 SCHOOL OF INFORMATION UNIVERSITY OF MICHIGAN Challenges and prospects

25 SCHOOL OF INFORMATION UNIVERSITY OF MICHIGAN Challenges n Costs incurred by developers are often borne by users –Generalized solutions can be too heavy n Inertia –Research practices evolve more slowly than technologies n Cultural conflicts –Engineering perspectives VS. computer science perspectives

26 SCHOOL OF INFORMATION UNIVERSITY OF MICHIGAN Prospects n Attempts to apply new technology are often framed in terms of familiar technology n First efforts are often awkward hybrids n It is hard to know where the seeds of greatness might lie...
