It should be noted that Warringah is pro amalgamation. IP Telephony is scalable and easy to migrate across areas with very little infrastructure costs. What is a considerable challege;
Operational: 1) integration of core operating systems
                   2) training of staff
                   3) familiarisation of amalgamated suburbs & the respective community
                   4) managing staff profile if needing to operate multiple shop fronts
                   5) performance management / acceptance of performance measures (of success)
 
Cultural:      1) all staff sharing the organisation’s values  
                   2) change management / staff rationalisation
                   3) familiarisation / acceptance of new identity
