Law of contract features - a brief note

Students of Engineering Management need to have knowledge in law of contract. I want to emphasize the following 4 features in law of contract:

1. an offer
2. an acceptance
3. consideration
4. intention to be legally bound

Besides the principles and definitions as related  to these 4 features, you need to study the relevant law cases. These law cases help you to have a more concrete understanding of these 4 features.
