 To allow this, we have given you a selection of issues describing new features for this coursework that, if implemented in full, constitute more work than you can reasonably achieve in the time available.  You must choose a subset of issues to implement, balancing the need to do enough work to achieve your target mark for the exercise with the amount of time it is possible and worthwhile to devote to the exercise.
 
-Each feature you implement is worth 10 marks if implemented perfectly against the criteria in the marking scheme.  However, we have set a cap on the number of marks you can achieve for the implementation of features.  This means that if you select too many features to implement, you will be wasting your time, as you will not be able to achieve more marks for the additional work done.  Your aim is not to work long hours in order to achieve more than is needed, but instead to think about how you can use your time effectively, to deliver the expected amount of value in the fewest person hours.

 Since this is a somewhat unsual approach to coursework, we have provided a spreadsheet that will help you in making your choice of features to implement. The spreadsheet will allow you to see the effects of your choices on the mark you will achieve, based on your predictions for the mark you'll be awarded for each individual component of the work.  The link to the spreadsheet can be found on Blackboard (under `Assessment & Feedback` > `Team Coursework` > `Team Coursework Exercise 2`).  You'll need to log in to your university Office 365 account to access it.
