Insurance company in Japan
Kanji Conversion Project
The company is one of the biggest insurance companies in Japan and is ranked 12 in Fortune 500. About 25% of the Japanese families are insured by this company.
The company migrated its Hitachi mainframe to IBM mainframe but kept the Hitachi representation of the Kanji characters. In a later step, the company decided to convert all the Hitachi Kanji structures in its applications and its data to IBM Kanji structure.
The reasoning behind this decision was to align the Kanji in the applications and the data with IBM standards and solve problems which were caused by using the different character set.
This project followed a previous project conducted by MOST to convert the company's COBOL / Natural / ADABAS applications to COBOL / DB2.
Customer requirements were:
100% preservation of business logic and screens
Transparency for end users and ongoing system operations
Full validation of impacted data
Preservation of performance in both on-line and batch
Minimum changes to the existing Cobol programs
Phased approach including co-existence between converted and not yet converted programs.
15,000 COBOL programs (Batch and CICS)
3,000 Sequential files
800 DB2 tables
Project Methodology and Timeline
The project consisted of 3 phases:
Phase 1 - preparation of the new technological infrastructure, tools customization & migration of 1 small subsystem
Phase 2 – conversion of subset of applications
Phase 3 – conversion of the remainder of the applications.
The project ran from October 2010 to November 2014
MOST Responsibilities (prime contractor):
Active participation in all project teams (2 senior people on-site)
Systems mapping for migration
Automatic generation of data conversion and data validation routines
Automatic generation of test drivers to test 100% of the data access patterns
All impacted applications went live as planned without any defects. Despite the concern of functional changes and screens changes the business has not been adversely impacted. The customer was highly satisfied.
