| A Team *CAN* Solve A Difficult Technical Problem

THE PROBLEM
The shuttle lifted off in a roar. There were flames, sound and vibration that would beat your chest like a drum as it made its way to orbit. It was massively powerful and highly complex machine. When it reached altitude, it orbited backwards, upside down, cargo bay doors open - AND - without only a tiny bit of fuel left.
You can see a problem with this elegant engineering solution. “How do we return the Orbiter to earth, land it on a runway of our choice and have a nice rollout (stop)?” If you were a future crew member, this might concern you. A large, and wildly diverse, dedicated, strong-willed and skilled team of physicists, mathematicians, aerodynamicists, fuel / rocket experts, crew members and even a few lowly engineers (including a younger Dave) were assembled as a project team to solve what became TAEM (Terminal Area Energy Management). If you’re interested in the math, you can download it at:

At first I just couldn’t understand what the other project members were talking about. It was all in English, just a completely different discipline. It was certainly a lifetime learning experience for me.
One key to the solution was clear from the start. Where it was, the Orbiter had a great deal of potential energy. This is the energy that an object has due to its position to other objects – the Earth in this case. The orbiter was at a great height! That potential energy could be converted to kinetic energy as the orbiter returned to earth, (the kinetic energy of an object is the energy due to its motion) but converting that potential energy to useful kinetic energy was a challenge. It couldn’t just fall!
My role in this was programming an analog computer. WHAT? Yes! It was a Pace231R. A beautiful machine. I worked closely with the team “programming” the latest equations. It was a great deal of fun patching in integrations, square roots, derivatives, and whatever best fit the latest group-derived equations. I’d often take a patch panel home and work on it until I fell asleep. The output of my patched-in equations drove rows of strip-chart recorders that the entire team examined for hours in a quiet that a librarian would be proud of.

| “Projects are the means by which NASA explores space, expands scientific knowledge, and performs research on behalf of the nation” – NASA Space Flight Program and Project Management Handbook. http://go.nasa.gov/1QPkK8Z (Free download)
Project Categorization
Not all projects at NASA are huge. Many are actually very small. As the handbook says, projects “Vary in scope and complexity and require varying levels of oversight (notice the key word OVERSIGHT). They are assigned a category based upon
- The project life-cycle cost estimate
- The inclusion of radioactive material
- If the system being developed is for human space flight
Personally, I never worked with a product of a project that had radioactive material included. But the other two categories – I have grown up in, work on and managed.
How are Projects Prioritized?
The first and absolute primary consideration is if the product of the project will be used for HUMAN spaceflight. That criteria out rules all others. Then the life-cycle costs are considered. It’s not the total in-house cost of the project that determines the degree of oversite, it’s the cost of design, acquisition of components, assembly, then putting the project’s product in the field and maintaining it. A PM’s first project will be small. But thrilling none the less. A young PM is subjected to all of the scrutiny and oversight that the most critical projects are.
The Value of Oversight (Standardized Reviews)
As the NASA project standard states: “These reviews are essential elements of conducting, managing, evaluating and approving space flight projects.” They are a combination of a marvelous learning environment and a way to ensure that each component of the project plan has been reviewed, understood and exposed to scrutiny.
To make sure all aspects of your project are reviewed, a “Standing Review Board” is brought in. This is a group of independent experts who assess and evaluate project activities, advise project managers and report their evaluations to the responsible organizations. They conduct independent reviews of a project and providing objective, expert judgments.
I freely admit that at first, it’s very scary to stand up in front of an auditorium of 100 plus experts and review your project’s “Magic 6” criteria. But after a while it becomes an adventure. I’ve told many people, that at first these standardized reviews feel like “Throw stones at Dave” time. But it wasn’t! Everyone was being constructive, lending their expertise and trying to help all of us succeed. With a large, experienced and expert audience, you can get concerns expressed that you would NEVER, EVER have thought of as a project team.
What is the value of these reviews?
The reviews provide the project (team) with an independent assessment of their plans, goals, techniques and risk assessment. EVERY AREA is open for inspection.
They provide NASA senior management with an understanding of whether:
- The project is on track to meet objectives
- The project is performing according to plan
- Impediments to project success are addressed
The PMBOK Guide
This type of standardized review is missing from the PMBOK guide (V5), but I wish they weren’t. A disciplined system of peer reviews, system reviews and reviews by experts may seem expensive, but are a great stakeholder communication tool, a project team communication tool and team-building exercise as well as insuring you’re doing the job to the best of your ability.

| NASA doesn't use the word "Portfolio" as PMI does, but divides large efforts into "Mission Directorates." There are:
- Aeronautics Research
- NASA's Aeronautics Research Mission Directorate works to solve the challenges that still exist in our nation's air transportation system: air traffic congestion, safety and environmental impacts.
- Human Exploration and Operations Mission Directorate
- The Human Exploration and Operations Mission Directorate provides the Agency with leadership and management of NASA space operations related to human exploration in and beyond Low-Earth orbit. (MY PERSONAL FAVORITE!)
- Science
- NASA's Science Mission Directorate and the nation's science community use space observatories to conduct scientific studies of the Earth from space to visit and return samples from other bodies in the solar system, and to peer out into our Galaxy and beyond.
- Space Technology
- The Space Technology Mission Directorate is responsible for developing the crosscutting, pioneering, new technologies and capabilities needed to achieve NASA's current and future missions.
Below the directorates are Programs (such as the Shuttle), then Projects. The projects vary greatly in size and complexity and require different levels of oversight. Each project is assigned a category based upon:
PROJECT AND PROGRAM OVERSIGHT
Oversight came in the form of *REQUIRED* standardized reviews, peer reviews and many others. Most interesting to Project Management are the project life-cycle reviews. These reviews are essential elements of conducting, managing, evaluating, and approving space flight projects
These reviews were HUGE affairs. Hundreds of attendees would appear to listen to the humble Project Manager present their status. The attendees included a group of independent experts who assess and evaluate project activities, advise projects and report their evaluations to the responsible organizations. They are responsible for conducting independent reviews of a project and providing objective, expert judgments.
These reviews could become very stressful for the PM. I've known people to "crack" under the pressure. But the purpose was not to stress the Project Manager it was to explore every area of the project and point out weaknesses, strengths, risks and more. I think of it as "PM School." After years of standing up to an auditorium-sized audience getting questions from experts in their fields, a PM becomes VERY GOOD at what they do.
THE PROJECT MANAGER IS RESPONSIBLE FOR PLANNING AND SUPPORTING THESE REVIEWS.
And, must present six assessment criteria for consideration and review.
More on that later.
