In Part 1, I explored issues and possible improvements to the blood bank’s questionnaire interface for each question. In this part, I’ll look at the end screen of the process.
The glaring issue with this screen is that it requires the user to remember each question based on a short, obviously programmer-named description like “BLD TRANSFUSION”. I question the need to review a dump of all the questions and answers. The progressive nature of the questionnaire and the ability to jump back and forth between questions provides the user adequate opportunity to review and change answers.
- Determine how necessary this end screen really is. How often do people use it? How often do users go back and change answers at the end? If it’s very low, get rid of it.
- Rather than show all questions, maybe show only those questions users skipped and give them another chance to answer.
- Change the format of the questionnaire to show multiple questions at a time, and progress through only a few screens where questions are grouped together by type. For example, travel, sexual activity, and disease exposure.
