APPLICATION ANALYSIS
Current Operational Scenario
2.5 Application Analysis
Application analysis compiles and organizes the information required to
create the technical software requirements for the customer. The application
analysis activities are based on the business case and management’s decision
to pursue the opportunity. This phase describes the software functionality
the customer needs.
The application designer needs specific information to make the best choices
in approach. As a guide to organizing the data, create the following:
• A written current operational scenario
• A written future operational scenario
• List of differences
The application designer must understand the customer’s problem before
starting the analysis.
2.5.1 Current Operational Scenario
The first step of the current operational scenario is to map the process of the
customer's targeted operations. The operational scenario is assembled to
ensure that sufficient information is available and that the details are
captured. This activity is a joint effort of the APT, sales account manager, and
the customer. The output of this activity gives a detailed description of what
is occurring in the customer’s process. Sometimes, the best way is to observe
and record what actually happens, what information is used, and who
reviews it. Break down each transaction, command, and a response to words,
numbers, or codes that clearly communicate instruction, information, or
status. Items such as bills of lading, work orders, delivery logs, trip logs, etc.,
highlight the information the customer uses to run their business.
Every person or function that operates in or on a vehicle is a potential
candidate for mobile computer use. Determine which functions have the
most positive effect on profits and efficiency.
2.5.2 Future Operational Scenario
The future operational scenario invokes cost savings or additional revenue
because of changing the process. The basis of value rests with the customer
and the concept of sufficient benefit of additional revenue, timely and
accurate data, or improved response time to emergencies, etc. Examples of a
couple of questions to ask are:
• Does the increased citation rate of each police officer offset the cost of the
system? Specifically, how long does it take to recover the system’s cost?
• Does the increased volume of deliveries offset the cost of the system?
This has two aspects: the first is deliveries to new customers and the
second is frequency of service for each customer.
