One of the key barriers to successful international market entry and development is the ability to satisfy the minimum viable commitment.  We define this as the inflexion point at which a venture begins to generate positive cash flow.  In our experience the commitment (time and cash) required to achieve this is almost always under-estimated.  However, when the commitment is made, the rewards can be significant.  Enterprise Screen, the Glasgow-based video communications company, has grown by a third following implementation of an international development strategy defined during a workshop facilitated by RML.  The company's response to the minimal viable commitment challenge has led to it acquiring a growing number of strategically significant US accounts and establishing two offices within the territory.
