Conclusion

Joe will be happy to see what we've done for him. We'll build a production release and let him try it out. Surely he'll have comments about how the user interface is crude and unpolished. There will be quirks that slow him down or aspects that he finds confusing. User interfaces are difficult to get right. So we'll pay close attention to his feedback and go back for another round. Next, we'll add actions to change employee details. Then we'll add actions to submit time cards and sales receipts. Finally we'll handle payday. This is all left to you, of course.
