Evaluation+and+review

= Evaluation =

Once the new system has been implemented and is in full use, the system should be evaluated (this means that we take a long, critical look at it).

 The purpose of an evaluation is to assess the system to see if it does what it was supposed to do, that it is working well, and that everyone is happy with it. Once the new system is made the designers will compare the final system with the system requirement to see whether the system meets the requirements or not.

The designers also have to check the limitations of the system like if there is a certain thing that the system can’t do like process certain data.

After the designers have built the system they need to see whether the system has any flaws that need to be fixed or if there are any improvements that need to be made.

The designers then have to evaluate the system to see if the customers and users are happy and to see if the system has any other improvements that need to be made. The designers can evaluate in many different ways 2 of the best way to evaluate users is to send out a questionnaire asking about system performance or a interview with system users.

After the evaluation the designers need to compare the new system with the old system to see whether the new system is making a difference to the users or not.

The designers need to see the new system in use and check if the new system is working properly and if the new system is working properly and to see if there are any users struggling with the new system.

Then designers need to see if the new system is more efficient with time than the older one.

The designers now interview the users to interview the system users to ask about how the system works.

Then the designers send out questionnaires to a larger amount of users to see if they are satisfied

Some results from the evaluation may require changes to either hardware or software hardware may be needed to be updated because:
 * Feedback from the users say that the current hardware is not efficient enough
 * Because new hardware comes to market making changes necessary
 * There are changes in company that require hardware to be replaced or updated

Software may be needed to be updated because…….
 * Feedback from end users show they are not satisfied
 * Changes to the companies structure or how the company works may need modifications to the software
 * Changes of legislation may require software changes.
