Planning a Solution

When planning to implement a particular solution, you must consider a number of factors.

The first is you must document the current status, so if your particular solution does not work, then you can reset back to the original state. Then you can implement your solution, taking notes of what settings or features were changed

For more complex solutions, you may wish to consider setting up a test environment and testing a particular solution inside the test environment and fully testing here, before attempting the fix on a production environment. This could be achieved by setting up a test network, using simulation software or by virtualisation.

For example, if a networking problem was found to be due to a faulty Network Interface Card, the planning stage may consist of determining and sourcing a suitable replacement. The implementing stage might consist of physically installing the Network Interface Card in accordance with relevant health and safety procedures. The testing stage may consist of checking that data is being transferred correctly and at acceptable speeds.

If a newly-installed device fails to operate correctly due to a driver problem, the planning stage may consist of determining and locating the correct driver. The implementing stage might consist of installing the driver and the testing stage might consist of checking that the device is now operating correctly and that there is no negative impact on other devices.

If a program which has been operating for some time suddenly fails then the planning stage may consist of determining any unexpected values or combinations in the input data. The implementing stage may consist of applying changes to the source code and recompiling. The testing stage may consist of ensuring that the program now runs correctly and that there is no adverse impact on any other part of the program.
