Answer and explanation:
values of agile manifesto are:
1. Individual and interactions over process and tools.
2. Working software over comprehensive documentation.
3. Customer collaboration over contract negotiation.
4. Responding to change over following a plan.
Customer collaboration is by far the easiest to implement given the very fact that we are able to communicate and collaborate with the customers in every step of the way during development ensuring that we produce exactly what the customer wants through continuous feedback
The hardest however is the responding change over plan agile value. This is indeed one of the most important as it ensures a dynamic system in development but not quite easy to implement given the need to make changes to features as at when required while sticking to and modifying plans as needed
