Stakeholder MatrixLogo Design Contest

No slogan

The Stakeholder Matrix website software platform provides big/medium corporations and government organisations with the functionality to properly manager their stakeholder and issues management strategies.
It has been built within a fully integrated website software platform, providing a very unique product offering in the market place.

We want the logo to be corporate looking.
We want to use no more than 3 colours.
We don't want to use red or purple.
We want black in each logo, all other colours are a possibility, but we would rank the colours in the following order,
Blue, orange, green, grey, white, yellow

Our product is the complete solution for our target audience. The symbol needs to represent "complete". Maybe this could be done using a 3d box or cube with puzzles pieces all put together perfectly.
We are happy for the designer to have full creative license.
We would like to see the logo have a symbol, as well as the Stakeholder Matrix words.
We plan on using the logo in 3 possible ways,
1. As the full logo with symbol and words.
2. Possibly just with the words.
3. The symbol as a watermark.
It needs to be very corporate, modern looking and professional.
