Requirements Gathering Techniques And Strategies For Macquarie University Dating System

Requirements Gathering Techniques

There are any requirement gathering techniques but the two selected techniques to be used to find out about the problem are;

• Questionnaires
• Interviewing

This technique of requirements gathering involves preparing a set of questions and giving it to respondents in order to get information from the respondents. Questionnaires can be administered though different techniques such as;

• Oral questionnaires- This questionnaires are administered to the respondents orally by the researcher.
• Printed questionnaires- This type of questionnaires are printed on a piece of paper and the respondents are given to answer the questionnaires.
• Online questionnaires- This questionnaires are prepared on a web form which respondents can access and answer the different questions by filling the web form.

Questionnaires will be used for requirements gathering for the Macquarie University Dating System (MUDS). The type of questionnaires that will be administered to the students are online questionnaires where by a web form with all the questions will be prepared and students will be given the link to take the questionnaire.

Administering questionnaires is one of the best techniques to use to collect additional requirements for this system. This is because use of questionnaires is a cheap and easy method to implement for the university especially because the questionnaire will be a web form which will be very easy to access for the respondents. Specifically using online questionnaires will make easy for the university to administer the questionnaires to a large number of respondents within a short period of time and using minimal resources. Quantifying the data will also be easy since the university can use existing tools to get information from the responded questionnaires.

This is another technique that will be used to collect data from the respondents. This technique will be used to facilitate questionnaires and to get more quality data from the respondents. There are three types of interviews;

• Structured interviews
• Unstructured interviews.
• Semi structured interviews

Structured interview involves administering a series of predetermined questions that interviewees answer in the same order.

Unstructured interviews involves conducting the interview with no set of predetermined questions. The interviewer determines the nature of the interview.

Semi-structured interviews- this type of interview is a combination of structured and unstructured interviews. For this type of interview, a set of predetermined questions is asked to the interviewees but more additional questions might be asked during the interview to get more clarification.

For MUDS requirements gathering semi-structured interview will be used to gather requirements. The reason for using semi-structured interviews is because this technique will be used interchangeably with questionnaires thus questions that will not have been captured in the questionnaires will be asked in the semi-structured interview. This techniques is also efficient to use because data analysis of the collected data will be easy.

The following phases are followed in order to gather requirements for MUDS;

• Data Collection phase
• Data analysis phase.

Collection of data is the first phase that will be conducted while during requirements elicitation. Collection of data will be done using the questionnaires and interviews as explained in section 1 above. After data collection is done the project team can proceed to the next phase.

Data analysis phase involves taking the data collected in the data collection phase and analyzing it in order to come up with the requirements of the system. All the data will be analyzed using laid out procedures to make sure that all requirements are captured during the analysis of the data.
