Answer:
lagged effect
Step-by-step explanation:
Integrated marketing communication is one that involves the use of all form of communication to obtain a more effective promotion by a company.
The use of combination of promotion tools gives a better effect than each one in isolation.
A major difficulty in measuring IMC is the lagging effect.
Lagging effect is the difference in time between when marketing effort is made and when customers respond to these efforts.
