A new app has been created for smartphones, but is unreliable due to some unknown coding errors. A group of testers has been asked to locate the errors and suggest, in a report, corrections that should be made to the code before the app is ready for sale. The testers have been given a list of milestones to record their progress. These are shown: Milestones to be reached: Check that the plan will solve the unreliability issue. Create a plan to correct the code. Create a theory as to which lines/areas/blocks/sections of code are causing the unreliability. Document the results of the testing in a report. Download and install app on the smartphone. Identify the problem with the code by running the app. Suggest corrections that could correct the unreliability. Test the suggested corrections. Test the theory to see if the unreliability can be replicated elsewhere. List, by writing the number of the milestone, the order in which these milestones should be reached by the testers.
