Step 6 :
Program maintenance




(Step 6: Program maintenance)










< Program maintenance >

is designed to ensure that
the program operates
correctly,
efficiently,
and effectively
Two categories of maintenance activities are the following:


1.  Operation.
2.  Changing needs.







Operation.

Operation activities concern on
locating
and 
correcting operational errors,
making program easier to use,
and 
standardizing software
using structured programming techniques. 
For properly designed programs,
these activities should be minimal







Changing needs.

Organizations change over time
and
their problems must change with them. 
Agile development starts with core program functionality
then,
expands until customer is satisfied with results.
