  2. Hey Suresh,

    You are already PMP certified now. You know this stuff better than me :)

    Now it's your turn to develop some quizzes for me that I can post on the blog. Many quiz participants expressed interest in Procurement Management. So, why don't you develop a quiz on the contract types?

    Looking forward to your contribution. Talk to you in office tomorrow.

    Thanks.

  3. Hi Harwinder,

    Did you get a chance to write an article on difference between Quality Control and Quality Assurance ? I couldn't find any in your notes section.

  4. Hi Syed,

    I don't think I have a separate post on this topic. I thought that the answers to the quiz question would be sufficient to cover this topic. Let me know if you have any specific doubts.

    Thanks.

    Thanks for all the help,

    Best Regards,

  6. Little late on this post. Have a question: if CMMI is quality assurance, how is peer review quality control??

    Peer review is a KPA in CMMI?

  7. Hello Ram,

    I'm not sure I understood your point clearly.

    Peer review is a quality control tool, and all quality control tools can also be used in quality assurance.

    1. Hi Manisha,

      I don't think so. Usually I write on topics that are somewhat obscure and not well explained in books.

      If you mention your queries on COQ, I can try to clarify them.

      You can also post them on PM Hangout if you want more space and convenience.

      Thanks for bringing this up.

      Best regards,
      Harwinder
