Hardware and measurement abstraction layers (HAL/MAL) generally have 3 types of users: test developers, power users and framework architects, each having potentially competing interests and objectives. While a tradeoff often exists between immediate usability, customizability, scalability, and level of abstraction, the success of a HAL/MAL is overwhelmingly determined by its adoption among test developers, who are by far the largest group of potential users.
