Software change - ESSeRE

Maintenance costs





Usually greater than development costs (depending

on the application: business application vs.

embedded real-time systems).

Affected by both technical and non-technical

factors.

Increases as software is maintained.

Maintenance corrupts the software structure so

makes further maintenance more difficult.

Ageing software can have high support costs

(e.g. old languages, compilers etc.).
