I started analysis and modifications of our Personnel system at the
beginning of September 1996.  Working by myself, I was able to finish
all modifications to the system by mid-December 1996 (3 and 1/2 months).

Each program and job was unit tested as its modification was completed.
However, after all modifications were completed, I also performed two
weeks of parrallel testing of all our nightly scheduled batch runs.
That is, after the users were off each night, the data would be copied
to a test account, all conversion programs would be run, and all nightly
batch jobs run against the converted data.  The output from the actual
production run was then compared with the output from the test run.

The implementation was done over Friday night/Saturday morning span and
things have run pretty smooth since then.  Only a few forgotten control
cards that didn't get modified caused a some problems.

The Personnel system is written in COBOL and VIEW/3000 and uses a
mixture of KSAM files and TurboImage databases.  The system contained
around 35 different date fields.  The average lines of code is around
1,000 lines per program.  The system also consists of REPORT/3000
programs and INFORM/3000 reports.  I ended up having to modify 164 COBOL
programs, 13 REPORT/3000 programs, 80 COPYLIB modules, and 75 jobs
(JCL).  In addition, 9 one-time only conversion programs were written in
order to convert the data in 3 TurboImage database, 11 KSAM files and
numerous other flat MPE files.  Other modifications included TurboImage
database schemas, VIEW/3000 screen layout changes, definitions of date
fileds in DICT/3000 and the re-saving of any INFORM/3000 report that
used dates.

As a side note, I did not use any 3rd-party tools, just an in-house text
scanning program and a lot of manual analysis of file record layouts.

Hope this helps.
