I work on interaction design for an engineering/design application. I would
like to get some feedback from the forum on how do you do your resource
estimates for your design tasks.
Most of the times we end up under estimating the resource required to do a
design and have trouble delivering our designs to the Development team on
time. We typically breakdown the design into smaller chunks, and estimate
the time and resources required on research, core workflow design, UI
design, error handling, usability tests, documenting the design, etc., but
still we do not get closer to a precise estimate.
