Change management is about constantly trying to meet passenger demands, and to understand the full consequences of doing so.

Meeting passenger demands
Good system support during the change management phase enables fast and accurate response to demands for changed capacity. It is possible to decide exactly how expensive it would be to postpone aircraft maintenance and to hire overtime crew in order to increase capacity. Furthermore, early recognition of cancellations or reduced capacity allows you to inform the passengers of cancellations and flight changes in advance.

It is also possible to utilize the change management phase for a more open planning process. By leaving production open and allocating more standbys, you can adapt to fluctuations in passenger booking.

Adapt to resource supply
Resources you thought were available during planning will eventually not be there when needed. Aircraft will require unscheduled maintenance, standby crew may be called upon making the rest of their roster illegal, etc. On-line access to resource information allows you to always produce feasible plans that meet passenger demand.

Don't commit resources until necessary
Addressing problems as they occur does not mean that you have to commit a solution right away. You can find synergies by waiting and addressing many problems at the same time. The solver will provide you with the best options of how to adapt to the changes. A version control system allows the changes to be communicated internally without disturbing crew or other departments more than necessary.

By waiting you will reduce the risk of having to cancel changes already communicated to the organization.

Crew Communication
The published plan may not cover all flights. Crew can therefore bid for open time. They can also request to swap flights with other crew members. This bidding can be done via the internet. Using the optimization tools it is then possible to continuously update the plan to match the crew members' bids for open time and trip-trading.

When it is time to communicate a change the crew member can be reached via their mobile phone, the internet, service screens, palm pilots, etc.
