Good Housekeeping

• Complexity reduction

• Redundant software elimination

(10% – 20%)

• Unused software source-code

elimination (20% – 30%)

• Functional and technical

transparency by CARE*

*CARE =Computer Aided Redocumentation and EvaluationSave up to 25% on software maintenance!

Cost cutting by:

(Re)contracting prerequisites

Source2VALUE Market Branch facts

• Worldwide over 70 - 90% of IT costs is spent on software maintenance

• Over 50% of these costs is spent on analyses due to:

– Multiple development environments– Multiple exploitation environments– Outdated design– Outdated documentation

Some facts:

Organizations should CARE 4 software maintenance!

Characteristics:

CARE 4 software maintenance documentation and evaluation roundtrips!

Source2VALUE Solution

Characteristics of Good documentation

• ‘Light but sufficient’– Only relevant information– Efficient and easy accessible

• High quality– Accurate, up-to-date,

Readable, to-the-point, well structured and verifiable

Source2VALUE Solution

UML regeneration

• Manual changes are keptunless there are changes in the same object.

• Visual tracking of changesinsight in possible effects of changes on higher level objects or diagrams.

Source2VALUE Solution

Redocumentation experience

• The time is right..• Clean sweep!

– 20 - 30% of software code available is unused

• Manage Change– Requirements Management– Product vs Process documentation

• Start at the most interesting components– Questionnaire– Metrics

(volatility, complexity,..)

• Project or line activity?

Source2VALUE Solution

Redocumentation experience(2)

• Team composition• Use of tooling

– Metrics– Cross Reference– Documentation (re)generation (UML)– Use Case editing

• Institutionalize the maintenance of documentation

– Important part of software engineering

CARE benefits?

SQM

• Asseses Software Quality• Long term benefit by improving

software quality• Reduction of future maintenance costs

Redocumentation(Cross Reference, Technical documentation, Functional documentation)

• Insight on a technical en functional level

• Improves analyzability, decreases costs of maintenance significantly
