The overburn chart in the iteration shows the number of unfinished task points each day, which can help us predict the completion of an iteration. This requires team members to keep the whiteboard up-to-date at any time.

The MS Java Virtual machine automatically treats the public method of a Java class as a method of a COM object.
Care must be taken to do some of the necessary data type conversions (for example, to convert a Java String to BSTR ' s).
This allows you to quickly build a basic COM component and run it.
