Select the four core values from below and post an original thread of 150 to 250 words each in this week’s discussion forum, which justifies why an item on the left might be more highly valued than its counterpart on the right.

Excerpt from the Agile Manifesto:

Through this work, we have come to value:

  • Individuals and interactions over processes and tools.
  • Working software over comprehensive documentation.
  • Customer collaboration over contract negotiation.
  • Responding to change over following a plan.

That is, while there is value in the items on the right, we value the items on the left more.
