Development Approaches
The phase in which you examine the problem to identify needs of the user
What is Defining the Problem?
Phased Conversion, Pilot Conversion, Direct Cut Over, Parallel Conversion
What are the Methods of Implementation?
To Produce Documentation, Test Data, Data Dictionaries and track Software Versions
What are functions of Case Tools?
It involves using existing modules to create a solution.
What is the RAD approach?
Involves gradually implementing the solution, modules at a time
What is Phased Conversion?
To give hypothetical data to modules and the entire system
What is the purpose of Test Data?
Where designing algorithms, User-Interfaces and choosing a programming language occur.
What is the Planning Stage?
Involves the complete and immediate conversion to the new system
What is Direct Cut Over?
A list of all variables in a program with a description of each
Data Dictionary
Identifying problems with the Solution and correcting them
What is Modifying the Solution?
The new system is fully installed but only some of the functions are used; the old system is used for the other functions
What is Pilot Conversion?
Reduces the size of IT departments need
What is a function of Outsourcing?
Excessive Development time, User Confusion, Developer Misunderstanding the Client, Insufficient Solution Analysis
What are disadvantages of the Prototyping Approach
The new system can be monitored for its use, and if not suitable, the old system can be used
Advantage of the Parallel Conversion
