Limitations of Pilot Studies

Alright they're pilot studies and not supposed to be as strict as experiments.However, I realised that my previous posts did not really discuss any weaknesses of these studies which will have to be improved upon if proper experiments are to be performed.

Blogging
The data it yielded is sorely in need of interpretation. A scale of some sort is needed if any SPSS or statistical procedures are to be implemented. Respondents tended to confuse the cost of obtaining info with the cost of using the information. e.g. Cost of finding out where to eat was recorded as the price of their meal, not the cost of asking their friends. To make things clearer, perhaps an additional column which seperates the two would be appropriate.

Focus Groups
While yielding valuable information, the focus groups were confined to a restricted group of people. Managers, IT professionals and MBA students more likely than not are more familiar with MDS than the rest of the population. If the target were limited to these groups of people, the market might not be large enough to support MDS.
Design should be intuitive (from OoBE) such that any person off the streets including ah bengs/lians, aunties, uncles etc should be able to use the device without hassle.
