Explain about the influence of warranty and political pressure in IS project.

Warranty:

When a system is being developed under contract, this frequently carries a warranty for a period of months, or perhaps for a year. When so, then assessment requirements to be made of what claims there could be against the warranty and some contingency must be built in to cover this.

Political pressure:

Frequently, estimators come under pressure to decrease their estimates therefore some timescale or budgetary constraint can be met. Resisting this needs a certain amount of willpower but this can be made easier when the estimates have been developed onto sound principles, therefore the argument does not degenerate in one person’s guess against another’s.
