Light augmentation, hand-picked is support to overall program manager and a few select specialities.
Heavy augmentation, hand-picked is overall program manager, PMO, several sub-project managers and some select specialities.
Light augmentation, system integrator, is overall program manager, PMO, several sub-project managers and some select specialities.
Heavy augmentation, system integrator, assumes use of SI team to manage project and supply relevant staff to this end.

Methodology. A number of subprojects, each of which may deliver with its own approach (typically agile of some sort), all coming together in basic working form for integration, release and migration testing. Gradual migration of customers. No specific estimate for loading historic data that does not conform to latest content and format. Key subproject is from software vendor, delivering the bulk of the implementation.
Functional scope. Regular BSS including customer service, order management, billing, revenue assurance, online, output management. Provisioning, network inventory and field force are assumed reused. Some flexibility exists as different vendors have different depth of functionality. Simple B2B included, advanced quoting, documentation of complex build-to-order products etc. are not.
Technical scope. Management of technical environment (but not the actual setup of environments - this is costed in hardware). Test environments etc. for existing systems are not included. Assume use of existing interfaces, i.e., only adaptation required is for dual operations. Data cleansing assumed to be marginal (as it is very situation dependent).
Organisation scope. Implementation, training and regular change management for affected departments. Additional staff for go-live. No specific estimate for securing leadership commitment. No estimate for implementing new process and instruction documentation systems.
