One of the best Project Management Books I've Read!
Format: Kindle
This was a really great read for many reasons. The focus on ensuring your project has a strategic purpose is so important these days, where Program and Project Managers need to make sure the projects they are leading are providing value to the organization. The framework is one that can be applied immediately with the explanation and tools provided in the book and on the author's website. The real-life stories and projects were not only fun to read, but very helpful in understanding how to apply the framework. The examples were very thorough and helpful. There is great information on what is needed from a PM to be successful including managing the team and stakeholders.
On top of all that, when I got to Chapter 10 it was like a bonus chapter for me. Chapter 10's focus is on "managing your inner game", and has great information on ensuring you have the right mindset to be successful. Project Managers have the opportunity (and challenge) to work with many different personalities and in many challenging environments. This chapter provides really great information on how to navigate those waters and be successful. Chapter 10 could seriously be a book in itself.
Chapter 12 was yet another bonus chapter, especially for lifelong learners. It's all about the idea of taking everything we've learned and applying it to our life. As the author states, our lives are essentially a project. Why not apply the same principles to ensure we are achieving our purpose and providing value, with yet again, really great examples to get us started.
Anyone who leads or is involved in any kind of projects or who wants to work better in a team environment would benefit from reading this book.

Strategic Management Made Simple and Effective
Format: Hardcover
I told Terry Schmidt that would be a better title for his book, “Strategic Management Made Simple and Effective”.
The time-tested Logical Framework Approach (LFA) that Terry champions goes far beyond project management. With its exploratory LogFrame matrix leading from inputs to outcomes, outcomes to purpose, and purpose to goal, the LFA forces you to understand the reason for the project. Projects are not executed for their own reason but to achieve something specific. The LogFrame traverses the ladder from inputs to goal through objectives with success measures, ways to verify success, and assumptions that must hold true be successful.
Terry adds his own concept -- that he calls the Implementation Equation™ -- to help you build the LogFrame: IF inputs AND valid assumptions, THEN outcomes / IF outcomes AND valid assumptions, THEN purpose / IF purpose AND valid assumptions, THEN goal.
This methodology offers you a way to view the LogFrame with multiple perspectives: scientific method, strategic planning, project management, risk management, management by objectives, and, although he does not mention it, also quality management.
In particular, his use of assumptions has helped me to redefine my view of risk management. Rather than brainstorm a large list of possible risks in a registry that becomes impossible to manage, I use the probability that the assumptions needed for success are not valid – and their impact on achieving success, as the true risks that must be actively managed.
A highly entertaining as well as informative book, “Strategic Project Management Made Simple”, or whatever you choose to call it, should be the first guide you reach for when building a portfolio, creating programs or products, or starting a project.

LFA is now the Project Manager's Super-Power!
Format: Hardcover, Format: Hardcover
This books is not just for PMs, it is also for people in operations that are facing the challenge of aligning the output of their day-to-day activities and multiple projects with the bigger picture of their enterprise.
Personally, what I liked the most (and which it has been very helpful) is the visualization and alignment of the strategy with the operational side of the business: Logical Framework Approach (LFA) -- I call LFA my hidden super-power!
Strategy is an abstract concept and often difficult to communicate to those responsible for the execution of the projects. Terry made this task very simple by addressing the most important aspect of any project: What are we trying to accomplish and Why?
