Idea for a model of school leadership

Our NPQH tutor talked with us about school leadership models. I was intrigued by an idea that she says is in place in a school somewhere in Bolton (but I can't find it anywhere on the internet).

The clearly defined roles of the leadership team relate to aspects of the private sector. 

For instance:

• Quality Assurance - This would relate to the quality of the teaching and learning. This person would take responsibility for ensuring that key standards are met and are consistent at all levels of a child's education.
• Product Design - In this case the product is the curriculum. This team member would have responsibility for the design of the curriculum, ensuring that it meets a design brief (decided by the children?). The product would need to be innovative, current and exciting in order to suit its target market.
• Communications and Marketing - This is all about communicating with key stakeholders and the community. Marketing may include a effective website and ensuring that parents are involved.

What other business terms could be used to define roles within a school management team?
