D383 - Build Core Testing Data for Prototyping
DEFINITION
The purpose of this activity is to set up the data scenarios to be used in the prototyping sessions.
SUMMARY
The process has two main parts:
- define needed data environment for prototyping, and
- develop prototype database.
Its objective is to:
- define a test environment, which mirrors the company´s real business situation, and
- build a basis for testing the prototype to actual business cases.
PATH PLANNING GUIDANCE
Normal practice for projects using prototyping design techniques.
DEPENDENCIES
Prerequisites (Finish-Start):
- Development environment - Process D130
Dependent procedures (Finish-Start):
- Iterative prototyping - Process D400/D450
RECEIVABLES
- Business process descriptions from project model
- Definition of business cases
- Source documents
- Data from systems to be replaced
- Paper files (e.g. customers, suppliers, material)
DELIVERABLES
- List of business processes to be prototyped
- Business cases to be prototyped
- Prototype Data Structures
- Content for each database or file structure:
- Database number/name
- Database file name
- Logical and physical record structures
- Brief description of data elements (length, format, valid values, etc.)
- Initial data values.
TOOLS
- Refer Application Software documentation
DETAILED DESCRIPTION OF TASKS
Define needed data environment for prototyping
This subtask serves to find business cases, which represent actual business scenarios. Based on the identified business processes identified in the Project Model (see processes R065 through R069) to be used in the prototyping sessions, incidents of those data entities to be used in the process should be identified in the organisation.
Responsibilities:
Project Mgt
|
Reviews list of business cases and collected test data
|
Project Mgt
|
Reviews list of business cases and collected test data
|
User
|
Identifies business cases and data incidents to be used in the prototyping database
|
Team/MIS
|
Helps users in specifying the right level of detail for data collection and understanding how to collect data
|
Develop Prototype Database
The purpose of this activity is to develop, implement, and populate the databases and/or file structures needed to support the prototyping process. This activity includes both the load of data through programs and utilities as well as the initial data entry required to establish desired prototype scenarios.
The objective of this task is to:
- create the database and file structures needed to support the prototypes to the level of sophistication determined by the prototype strategy, and
- populate the databases and file structures with the data needed to support the test cases identified.
Worksteps:
- Review Application Software technical documentation
- Identify required databases and file structures
- Load and configure databases and file structures
- Set initial file setting required for scenarios to be prototyped
- Populate databases as required by test cases.
Information Sources:
- Vendor project team
- Site and vendor technical documentation
- Site standards and procedures
- Application software
- Technical Product Specification (Solution Strategy)
- Application software Prototyping Plan
- Prototyping Schedule
The deliverables from this task are:
- Prototype Data Structures (Create)
- Content for each database or file structure:
- Database number/name
- Database file name
- Logical and physical record structures
- Brief description of data elements (length, format, valid values, etc.)
- Initial data values.
SCOPE:
|
Entire prototype
|
DETAIL:
|
Sufficient to specify physical data structures with the prototyping tool in use.
|
FORMAT:
|
Input to prototyping tool, with supporting diagrams and text as documentation.
|
Responsibilities:
Project Mgt
|
Reviews data management work
|
Data Mgt
|
Creates library and allocates storage space for the system database; develops and executes the data definition language to create the structures in the database management system
|
User
|
Identifies business cases and data incidents to be used in the prototyping database. Enters applicable test data
|
Team/MIS
|
Develops code and executes programs to load initial test data into database files
