//**i) IDENTIFY and JUSTIFY the conversion method for the designed multimedia system. **//

The conversion method that will be used for this mulitmedia system is __**DIRECT CONVERSION. **__ Direct Conversion involves immediate change to the new system on a date chosen by the company. On this date the old system is phased out completely and the new system takes over. Direct Conversion is an effective conversion method for this multimedia system as all the information used in the previously system is directly moved over into the new system without delays. This multimedia system will replace the companies old system of advertising via posters on Sydney streets. This method is effective as there are very minimal transition costs due to their being no phasing time. The system will enable the customers, workers, authors and all those involved to view the site at anytime. The information presented will no longer be static, it will now be dynamic and constantly changing.

//**ii) COMPARE the conversion method chosen with other conversion methods and JUSTIFY how the participants will be affected by the chosen conversion method when the multimedia system is in use **//.

__Parallel Conversions-__ involve the new system and the old system working together at the same time. This allows the participants to compare both systems and get a good understanding of both systems, and if there are any problems with the new system these can be ironed out before the old system is completely phased out. Parallel conversion, however places extra work on the participants as both systems require operation, as well as this there could be confusion amongst the participants about which system has the correct data to be used. __Phased Conversions-__ involves a gradual implementation of the new system. This means that certain parts of the new system are implemented whilst the remaining parts continue to run on the old system. Each phase is implemented once it is up and running successfully. For example stage one is implemented, it runs successfully, then phase two is implemented and so forth. This process continues until the whole system is implemented. __Pilot Conversions-__ involves trialling a new system in a small portion of the organisation. The old system is still in place so therefore if any issues arise the data can be retrieved. Pilot systems are often used as a way to entice participants into a new system. Those participants who are eager and willing to change from the onset change to the new system, then act as guides for those participants that may have issues. __Direct Conversion__ will affect the participants in many ways, including the workload on adjusting to a new system directly at the onset of its implementation, the learning of the new system and how it runs, the benfits it will bring and its faults, the customers and authors will benefit from this new system as the information will constantly be updated, this allows individuals to view the site anytime and anywhere, from their mobile phones, laptop computers and various other portable devices.
