JAD session excerpts
Alan Marks (store mgr): I am so excited to be launching this new service to our customers! It’s going to be great to not have to refer out customers to unknown service companies. Besides, if they can’t fix their own appliance, we might be able to convince them to visit the store to replace it.
Emily Johns (service manager): Yes, I agree! We need to work very closely with the parts department in order to get the service estimates out to the customer and get the parts for the repair quickly.
Meredith Parks (programmer): I think it would be a good idea to name our new service system. Any ideas?
Alan Marks (store mgr): Service Information System? SIS?
Emily Johns (service manager): Service Information Manager? SIM?
Meredith Parks (programmer): OK, let’s vote.
Meredith conducts a quick vote and all are agreed on SIM.
Maddox Farley (parts director): I’m a little worried about how this SIM will affect my inventory levels.
Meredith Parks (programmer): I need you to break this down a bit for me. Who is involved in this new process?
Emily Johns (service manager): We definitely have the customers, parts department, parts, technicians, appointment setters, and calendar.
Meredith Parks (programmer): OK, now we have our entities. What are the processes that will take place?
Alan Marks (store mgr): Well, we will need to generate estimates and final invoices.
Emily Johns (service manager): Right. And we’ll make appointments, order parts, assign technicians to appointments.
Meredith Parks (programmer): Anything else?
Emily Johns (service manager): A calendar should be able to be viewed or printed for each technician. Each technician needs their daily schedule of appointments at the beginning of each day.
Alan Marks (store mgr): I don’t think so. Payment will be accepted by the current cashier’s system.
Meredith Parks (programmer): OK.
