1.A-Current Situation: The Problem to Be Solved

What is the problem in the current situation?

    Examples:

    the response time when playing letter-chess is far too slow. (Change SW for new technology-new in solution domain-)

    I want to play Go, but cannot find players on my level. (Application domain)

What has changed? Why can we address the problem now?

there has been a change, either in the application domain or in the solution domain

    Change in the application domain

    A new function (business process) is introduced into the business

    Example: We can play highly interactive games with remote people

    Change in the solution domain

    A new solution (technology enabler) has appeared

    Example: The internet allows the creation of virtual communities.
