The determination of these elements was based on Strategic Communication Model by Barret (2002). Barret's model has been modified by adding two more elements namely communication planning and work culture. For the purpose of this study, a total of 28 complaints about commuter services sent via email by KTMB customers were collected and analysed.

Through correlation analysis, the study found that there is a positive relationship between communication patterns and strategic communication. Meanwhile, regression analysis showed that strategic communication elements had influence a total of 56 percent variant towards effectiveness of message delivery.
