Unit 22 People in Computing

Requirements: need to, have to, must, be + essential, critical

Note how we describe requirements for particular jobs: You need to be able to empathise with the person at the other end of the phone. IT managers have to take responsibility for budgets. You must be interested in your subject. You must have worked for at least two years in systems analysis. Experience with mainframes is essential/critical. We can describe things which are not requirements like this: 6. You don't need to have a degree in computing science.

We can also treat need as a modal verb and use the negative form needn't: 7. You needn't have a degree in computing science. Have to is an ordinary verb. Its negative form is made in the usual way: 8. You don't have to be an expert in everything. Mustn't has a quite different meaning. It means it is important not to do something. It is used for warnings, rules and strong advice. For example: 9. You mustn't make unauthorised copies of software.
