One of the major problems with project work is the length of time it takes to complete. This applies to small structured projects as much as the larger unstructured project components. For example, three OU undergraduate social psychology mini-projects comprising an observation exercise, content analysis and an attitude scale were expected by staff to take about the same time as an

ordinary essay, but actually took three to four times that long. An educational case study involving administering three tests or inventories to one individual and writing a report took three to four times as long as an essay, and a project requiring students to administer three questionnaires to a class and analyse the results took five to six times as long. Unstructured projects can expand indefinitely.
