Why I Created The Tao of Mission Assurance

For most people outside the aerospace world, the phrase Mission Assurance means very little. Even inside the industry, it is often misunderstood.

Some assume it is simply quality control. Others think it is bureaucratic oversight, merely a set of checklists imposed on engineers and program managers. Occasionally, it is treated as an expensive luxury, something that can be trimmed when schedules tighten or budgets shrink.

In reality, Mission Assurance is something much more fundamental.

Mission Assurance is the practice of increasing confidence that a mission will succeed. It is the discipline of understanding risk: technical risk, programmatic risk, and operational risk, and managing that risk deliberately across the entire lifecycle of a system.

It is the quiet work that makes success possible.

And right now, it is more important than ever.

Why This Matters Now

The global space industry is expanding at a pace few imagined even twenty years ago. Commercial launch providers, new satellite constellations, reusable rockets, and rapidly evolving technologies are transforming how space systems are designed, built, and deployed.

What was once a domain dominated by a handful of government programs has become a vibrant and competitive ecosystem of public agencies, private companies, and international partners. Missions that once required a decade to develop are now expected in a fraction of that time.

Speed has become a defining feature of modern space development.

Cost has become a driving constraint.

And innovation has accelerated dramatically.

These changes are exciting, and they have unlocked remarkable progress. But they also introduce new challenges. The faster we build and deploy space systems, the less margin we have for error. The more dependent society becomes on space-based services (navigation, communications, weather monitoring, national security, financial systems, etc.) the more consequential failure becomes.

Space remains an unforgiving environment. The physics have not changed. Hardware still fails. Software still behaves in unexpected ways. Supply chains still introduce uncertainty. And once a spacecraft leaves Earth, there are very few opportunities to fix what went wrong.

Mission Assurance exists to confront these realities.

Yet at the very moment when the complexity of our systems is increasing, something else is happening within the profession.

The people who built Mission Assurance are retiring.

Across government agencies, aerospace companies, and research organizations, the generation that established the standards, practices, and culture of the field is gradually stepping away. Many of these professionals learned their craft through experience gained in the aftermath of difficult lessons, lessons written in the history of aerospace failures and hard-earned recoveries.

Their knowledge represents decades of institutional memory.

And much of that knowledge risks being lost.

This emerging gap between rising system complexity and declining institutional experience is one of the reasons I began writing The Tao of Mission Assurance. 

A Profession That Comes and Goes

Mission Assurance has always lived in a strange cycle.

When a major aerospace failure occurs, the profession suddenly becomes visible. Investigations uncover overlooked risks, flawed assumptions, or breakdowns in communication. New standards are written. Oversight increases. Investment rises.

For a time, Mission Assurance becomes central to the conversation.

But as memories fade and new programs begin, attention gradually shifts elsewhere. The discipline once again becomes quiet background work, something that only specialists think about.

Until the next failure reminds everyone why it matters.

This pattern has repeated itself throughout the history of aerospace development. The profession grows in response to tragedy, matures through experience, and then slowly recedes from view as other priorities take center stage.

Today we find ourselves in another transitional moment.

Commercial innovation has demonstrated that faster development cycles and lower-cost architectures are possible. This has challenged many traditional assumptions about how space programs must operate. In some circles, it has even led to the perception that Mission Assurance itself is outdated.

But that interpretation misses the point.

Mission Assurance is not about slowing innovation. It is about enabling it responsibly.

Risk can be accepted. It must be, if we are to push technological boundaries. But risk should never be ignored, misunderstood, or left unmanaged.

Mission Assurance provides the tools and perspective needed to make those tradeoffs wisely.

The Mission Assurance Manager

At the center of this discipline is a role that many outside the field rarely notice: the Mission Assurance Manager.

A good Mission Assurance Manager does not simply enforce rules. The role is far more nuanced than that.

A Mission Assurance Manager is a systems thinker, integrating insight from multiple technical disciplines such as, reliability engineering, quality assurance, safety, software assurance, supply chain risk management, cybersecurity, and more. They bring together information from across a program to understand how risks interact and where vulnerabilities may exist.

They act as both advisor and conscience for the program.

Their responsibility is not to stop progress, but to illuminate the consequences of decisions. They help program leadership understand the relationship between cost, schedule, performance, and risk.

When they do their job well, the mission succeeds, and their contribution often goes unnoticed.

When they are absent, the consequences can be severe.

Why This Website Exists

This website exists as a place to explore that idea.

It is a place to discuss the history of the profession, the lessons learned from past missions, and the evolving challenges facing modern space programs. It is also a place to reflect on the human dimension of Mission Assurance: the leadership, judgment, and professional integrity required to do the job well.

Most importantly, it is meant to help make the discipline visible again.

Mission Assurance has never been the most glamorous part of aerospace. But it has always been one of the most essential.

If this project succeeds, it will do three things:

It will help younger engineers understand what Mission Assurance truly is and why it matters.

It will provide current Mission Assurance professionals with a broader perspective on the role they play within complex programs.

And it will help program managers, engineers, and leaders across the industry better understand how Mission Assurance contributes to mission success.

The Book

The book The Tao of Mission Assurance is an attempt to capture the philosophy, practice, and leadership of this profession at a moment when it is evolving rapidly.

It is not a textbook, and it is not simply a collection of standards.

Instead, it is a reflection on how Mission Assurance works in the real world. How professionals navigate competing priorities, manage uncertainty, and protect missions that often represent years of work and billions of dollars of investment.

More importantly, it is written for the next generation of Mission Assurance professionals.

Because the future of space systems will depend not only on brilliant engineering, but on the thoughtful management of risk.

And that is the true work of Mission Assurance.
