Chapter 2
System Planning Process
This chapter covers the system planning preparatory process. Adding a
Private DataTAC™ network to an existing computer system requires more
than new hardware. Mobile computer and host application software issues
must be considered.
2.1 Scope
This chapter discusses high-level issues that must be addressed before
designing a Private DataTAC network. This manual does not cover all issues
relevant to a business case, an application analysis, or a formal SOW. Other
documents, both at the procedural level and product specific, address these
details. (For other documents that address these details, see “References” on
page xix.)
Managing the solution requires the skills and talents of several individuals
working as a team. This group is the solution team. The team approach is
used because of the large volume of detailed information to be determined,
shared, and commonly understood. The solution team for this phase
includes:
• Sales and the Advanced Products Team (APT)
• Systems Engineering
• Project Management
• Application Software Engineering
• Systems Technologists
• Business Development
2.2 System Planning Process Overview
The system planning process starts with the business case. The business case
could be the result of a Request for Proposal (RFP) or a Request for Quote
(RFQ). The business case contains the basic elements of customer
qualification, budget availability, time tables, and basic technical
requirements. At this level, the account manager creates a needs analysis
based on a series of questions to the potential customer, what the customer
requires, and any relevant information in the RFP or RFQ. The needs analysis
helps management decide if this is a feasible project. If the project is feasible,
the group advances to the system analysis and application analysis phases.
