24. Interestingly, the original independent 2001 report on the costing exercise on the Bill noted: "capacity is an important consideration in transformation (human capacity, financial capacity, information technology, etc). But current capacity should not dictate the destination that the Child Justice Bill wishes to achieve. ... Current capacity does however influence the trajectory of the implementation strategy to achieve the specified objective". An important consideration is that people tend to seek to invest time in learning how a new system works only if that system is a reality in their lives. "So long as the implementation of the system is being planned so people will only plan to learn how it works some time in the future, i.e. capacity will not be developed without some external pressure." The report also rejects a big bang approach, which, it says, could severely compromise service delivery but acknowledges that dividing the actual implementation into a number of phases is a challenge. The report also suggests that a systemic approach will probably require a reasonably long roll-out period, requiring a project management approach. The implementation plan will also need to be reviewed regularly. Obviously, there will be major costs in implementing the Bill, but over time, experts argue, there will be financial savings for the government.
