A more thorough explanation:

An effective assignment is a task or project that is completed successfully and achieves its intended purpose. It refers to the ability to complete an assignment in a way that meets or exceeds the expectations of the person who assigned it.

• Completing a research paper that meets all the requirements and earns a high grade
• Finishing a work project on time and within budget
• Creating a presentation that effectively communicates the desired message to the audience

These examples illustrate effective assignments because they were completed successfully and achieved their intended purpose. In each case, the person who assigned the task was satisfied with the outcome.

The effective date is the date on which a law, contract, or other legal document becomes enforceable or takes effect. It may be different from the date on which it was signed or enacted.

A new law is signed by the governor on January 1st, but it may not take effect until July 1st. The effective date is July 1st, even though the law was signed earlier.

This example illustrates the concept of effective date by showing that the date on which a law is signed is not necessarily the same as the date on which it takes effect. The effective date is the date on which the law becomes enforceable.
