All costs Labour Hours actually incurred in the performance of the tasks AC are accumulated at a level which will identify the cost elements and factors contributing to cost variances. Option 1 shows a situation where the value quantity of work actually achieved is greater than the quantity planned to be achieved to date. Similarly, to cause a desirable change in the trends, specific changes in the project need to be made. The servicing schedule is optimised but Engine 2 dates are substantially later than planned when the baseline schedule was stored. All elements of the work are to be scheduled into a logical sequence. The productivity of the workforce can change on a daily basis.

The focus of the paper is on the underlaying philosophy of the VIPER process and its potential to be applied to other business endeavours that manage complex resource limited schedules on a routine basis. Each of the processes necessary for a complete application of the method is explained while providing an elaboration of the as44817 as relevant to each of the processes and a guidance section, attempting to provide further clarity to the correct and incorrect aspects of executing the process.

S tandards Australia is an independent, not-for-profit organisation, recognised by the Australian Government as the peak non-government Standards body in Australia. These measure of performance should be established in such a way that they correctly measures accomplishment of in-progress tasks.
VIPER integrates maintenance data, timesheet data and hangar floor reports; using sophisticated data integration and aw4817 techniques, including automated data capture processes, to deliver an integrated management and control system. Not all packages contain the ae4817 work described above.
The advantages of using software to manage aircraft maintenance. The primary source of data used in this paper is the personal observations of the authors based on a direct involvement with the development and implementation of VIPER and its predecessors of the last as8417 years. Setting the objective measures in advance enhances accountability and objectivity.

The initial systems were developed under the auspices of Australian Defence Force ADF managers as they sought to respond to some of the business pressures outlined above. Earned Values EV for tasks, elements, and totals are compared with the corresponding Planned Value PV to identify any variance between the amount of work accomplished and the amount of work scheduled.
This measure was selected to deal effectively with the unique problems associated with maintenance work. Qs4817 majority of the standard, as you would expect, is dedicated to detailing the steps necessary for adequate application of the EVPM method. In addition the current schedule shall be progressed to show achievement and to provide forecast completion dates as481 the scheduled work.
The standards then available did not lend themselves to simple business requirements as48817 designed for major defence acquisition projects and as a consequence, FPM developed processes and reports to meet the requirements of VIPER users. Comments The value of work achieved Earned Value is based on the original plan. Forecasts of the scheduled completion should also be routinely developed and updated based on past trends and current knowledge for comparison with the planned completion dates.
An interesting but not impossible challenge! The effect of this change is to move the responsibility for the various aspects of management control and reporting from potentially artificial positions and processes often created for the sole purpose of achieving compliance ; to the organisations normal line and project management positions and processes, ie the people and processes that actually control the project.
In either case, revisions to planning should only be accomplished prospectively. The primary purpose of VIPER [1] is the management of airworthiness issues associated with the validation, control, and tracking of maintenance data essential for the safe repair of aircraft and other capital assets although these are only briefly mentioned in this paper. In order for the Project Manager to exercise proper control of the project, the chain of authorisation for the commencement of work should emanate from the Project Manager either directly or indirectly.

On the other hand, the quantity of labour used on the servicing is far more predictable and controllable. Department of Defence Australia. As417 me of follow-up comments by email. Forecasts at completion both in terms of cost and schedule are made for comparison with current period status information and performance Reports are distributed to appropriate management levels on a consistent and periodic basis.
