When can use the Questionnaire?• So, you can consider using questionnaire if :

– The people you need to question are widely dispersed– A large number of people are involved in the system

project – You wish to be certain that any problems with the

current system are identified and addressed in follow-up interviews.

Getting Started• Before you start to design a questionnaire,

identify its objectives. • More specifically, identify what kind of

information you want to obtain. • Then brainstorm – write down all possible

questions for incorporating in the questionnaire.

Questions Types• Open Ended Questions,

– It require more thought and more than a simple one-word answer, e.g,

• Describe…. ?,

• List the most frequent problems ….?,

• Why…. ?, ………etc

• Close Ended Questions– It require a simple yes/no answer or the respondent is

asked to choose one of the answers,

Well Designed Questionnaire (How ?• In constructing the question:

– Keep questions simple, • avoid ambiguous, double-barreled and hypothetical

questions,

– Avoid words of more than three or four syllables and over-long sentences.

– In closed questions, allow the respondent the option of answering with ‘not appropriate’, ‘don’t know’ or ‘have no strong feelings’.

– Avoid overly sensitive questions – you are unlikely to get a ‘true’ response.

• In the general design,– Start with a brief sentence to explaining the purpose of

the questionnaire, and what the data will be used for.– A good questionnaire has a clear and coherent

structure• questions dealing with similar aspects should be grouped

together

• develop a logical order of questionnaires.

– Do not leave important questions to the end of questionnaire.

– Do not split questions over pages, or ask questions that require answers to be completed on subsequent pages.
