Level-1 Diagrams (Create four total; one for each process on the level-0 diagram)
Also, work on the following items.
Petrie’s Electronics needs to improve its marketing and customer retention by increasing customer loyalty. The marketing department is in need of a Customer Relationship Management (CRM) system. Upper management has selected No Customer Escapes as the top Information Technology project this year.
2. In order to gather detailed requirements, we will need to do the following.
a. Continue reading in our book. Last week we read Chapter 3 and 4; this week we must understand all of the concepts in Chapters 5 and 6.
b. Read the Petrie’s Case Questions at the end of Chapter 5 and 6 to add to what we learned in previous weeks.
c. We have already gathered some requirements and constraints identified in PE Table 5-1, on page 150 of our textbook.
3. We will validate the requirements in Table 5-1, and gather additional requirements by using:
a. Traditional method for Determining Requirements.
Review existing documentation as described by Table 5-1 on page 125 of our textbook.
b. Modern Methods for Determining Requirements.
Joint Application and Design sessions.
c. Radical Methods for Determining Requirements.
Business Process Reengineering (BPR).
4. To better understand a process for requirements gathering, we should review how Pine Valley Furniture will determine requirements for their Web store project (pages 143?146) in the book.
5. The Petrie’s Electronics Case in Chapter 5 on pages 150?151, describes how you will collect requirements for the CRM project. The Project Manager has decided not to build the system in-house, but to research current customer loyalty systems in use in the market place today. Sanjay was tasked to find three possible alternatives as described in PE Table 5-2 on page 151.
