Your problem analysis will have identified the key stakeholders and users you will need to interview to gain an understanding of the stakeholder's needs. Typically, it does not take many interviews to get a solid understanding of the larger issues. The Analyst's Summary: 10 + 10 + 10 |
![]() | The last section of the interview form, The Analyst's Summary, is used for recording the three most important needs or problems uncovered in the interview. In many cases, after just a few interviews, these highest-priority needs will start to be repeated. This means that you may be starting to get convergence on some common needs. This is to be expected, especially among those users or stakeholders who share a common perspective. So, ten interviews will often create only 10 “15 different needs. This is the start of your requirements repository , a set of assets you will build and use to good advantage over the course of your project. This simple, inexpensive data, even by itself, will help you and your team build a solid foundation with which to initiate your project. |
![]() | The HOLIS team decided to have the marketing team (Rick and Alyssa) develop the questions for the interview but wanted everyone on the team to experience the process. That way each team member would have the opportunity to meet customers face-to-face and thereby "see" the problem and a potential solution from the customer's perspective. So, the team divided up the customer and distributor list and had each team member interview two people. The team used The Analyst's Summary to summarize the needs that were provided and weeded out the duplicates. After fifteen interviews, the team had identified about twenty needs to fill in the top of the requirements pyramid. |
