Dyman Associates Risk
Management – As a management process, risk management is used to
identify and avoid the potential cost, schedule, and performance/technical
risks to a system, take a proactive and structured approach to manage negative
outcomes, respond to them if they occur, and identify potential opportunities
that may be hidden in the situation [4]. The risk management approach and plan
operationalize these management goals.
Because no two projects are
exactly alike, the risk management approach and plan should
be tailored to the scope and complexity of individual projects. Other
considerations include the roles, responsibilities, and size of the project
team, the risk management processes required or recommended by the government
organization, and the risk management tools available to the project.
Risk occurs across the
spectrum of government and its various enterprises, systems-of-systems, and
individual systems. At the system level, the risk focus typically centers on
development. Risk exists in operations, requirements, design, development,
integration, testing, training, fielding, etc. (see the SE Life-Cycle Building
Blocks section of this Guide). For systems-of-systems, the dependency risks
rise to the top. Working consistency across the system-of-systems,
synchronizing capability development and fielding, considering whether to
interface, interoperate, or integrate, and the risks associated with these
paths all come to the forefront in the system-of-systems environment. At the
enterprise level, governance and complexity risks become more prominent.
Governance risk of different guidance across the enterprise for the benefit of
the enterprise will trickle down into the system-of-systems and individual
systems, resulting in potentially unanticipated demands and perhaps suboptimal
solutions at the low level that may be beneficial at the enterprise level.
Dealing with the unknowns increases and the risks associated with these—techniques in the Guide's section on Enterprise Engineering,
such as loose couplings, federated architectures, and portfolio management—can help the MITRE SE alleviate these risks.
Risk Management in System-Level Programs
System-level risk management
is predominantly the responsibility of the team working to provide capabilities
for a particular development effort. Within a system-level risk area, the
primary responsibility falls to the system program manager and SE for working
risk management, and the developers and integrators for helping identify and
create approaches to reduce risk. In addition, a key responsibility is with the
user community's decision maker onwhen to accept residual risk after it and its
consequences have been identified. The articles in the Risk Management topic
area provide guidance for identifying risk (Risk Identification), mitigating risks
at the system level with options like control, transfer, and watch (Risk
Mitigation Planning, Implementation, and Progress Monitoring), and a program
risk assessment scale and matrix (Risk Impact Assessment and Prioritization).
These guidelines, together with MITRE SEs using tools such as those identified
in the Risk Management Tools article, will help the program team deal with risk
management and provide realism to the development and implementation of
capabilities for the users.
Risk Management in System-of-Systems Programs
Today, the body of literature
on engineering risk management is largely aimed at addressing traditional
engineering system projectsthose
systems designed and engineered against a set of well-defined user
requirements, specifications, and technical standards. In contrast, little
exists on how risk management principles apply to a system whose functionality
and performance is governed by the interaction of a set of highly
interconnected, yet independent, cooperating systems. Such systems may be
referred to as systems-of-systems.
A system-of-systems can be
thought of as a set or arrangement of systems that are related or
interconnected to provide a given capability that, otherwise, would not be
possible. The loss of any part of the supporting systems degrades or, in some
cases, eliminates the performance or capabilities of the whole.
What makes risk management in
the engineering of systems-of-systems more challenging than managing risk in a
traditional system engineering project? The basic risk management process steps
are the same. The challenge comes from implementing and managing the process
steps across a large-scale, complex, system-of-systemsone
whose subordinate systems, managers, and stakeholders may be geographically
dispersed, organizationally distributed, and may not have fully intersecting
user needs.
How does the delivery of
capability over time affect how risks are managed in a system-of-systems? The
difficulty is in aligning or mapping identified risks to capabilities planned
to be delivered within a specified build by a specified time. Here, it is
critically important that risk impact assessments are made as a function of
which capabilities are affected, when these effects occur, and their impacts on
users and stakeholders.
Lack of clearly defined system
boundaries, management lines of responsibility, and accountability further
challenge the management of risk in the engineering of systems-of-systems. User
and stakeholder acceptance of risk management, and their participation in the
process, is essential for success.
Given the above, a program
needs to establish an environment where the reporting of risks and their
potential consequences is encouraged and rewarded. Without this, there will be
an incomplete picture of risk. Risks that threaten the successful engineering
of a system-of-systems may become evident only when it is too late to
effectively manage or mitigate them.
Frequently a system-of-systems
is planned and engineered to deliver capabilities through a series of
evolutionary builds. Risks can originate from different sources and threaten
the system-of-systems at different times during their evolution. These risks
and their sources should be mapped to the capabilities they potentially affect,
according to their planned delivery date. Assessments should be made of each
risk's potential impacts to planned capabilities, and whether they have
collateral effects on dependent capabilities or technologies.
In most cases, the overall
system-of-systems risk is not just a linear "roll-up" of its
subordinate system-level risks. Rather, it is a combination of specific lower
level individual system risks that, when put together, have the potential to adversely
impact the system-of-systems in ways that do not equate to a simple roll-up of
the system-level risks. The result is that some risks will be important to the
individual systems and be managed at that level, while others will warrant the
attention of system-of-systems engineering and management.
