Process Capability Pro Overview
The Process Capability Pro software tool allows the User to generate a list of recommended
Mission Assurance process activities based on specified program processes and process
capability levels.
The Mission Assurance program covers Reliability, Maintainability,
Availability, and Dependability (RMAD), System Safety, and Quality Assurance (QA)
programs. This tool is complaint with S-102 Mission Assurance Standards.
Project files from Program Processes Pro software tool (i.e., files with extension *.pppf) can be
opened in the Process Capability Pro software tool. The Program Processes Pro tool helps to
identify the set of recommended S-102 Mission Assurance Standard processes that are
commensurate with a User defined product unit-value. When opening Program Processes Pro
files with Process Capability Pro, the recommended processes will be carried over and
recommended process capability levels by life cycle phase will be automatically assigned to
complement the set. For more details, see section 1.2.3.1.2 of this User’s Manual.

software component; [4] [Human reliability] procedure (operational or maintenance) or process
(manufacture or design) that is improperly followed;
NOTE: [1] An accident may cause a fault; [2] A fault may cause a failure; [3] A fault does not
necessarily require failure.
2
Definition source: IEEE 100, The Authoritative Dictionary of IEEE Standards Terms
25
hazard
a condition that is prerequisite to a mishap and a contributor to the effects of the mishap.
NOTE: A single point failure mode (SPFM) item is a hazard with respect to its potential to lead
directly to loss of a safety-critical or mission-critical system function.
maturity level
measure of the degree of accuracy of a data product, as developed using a specified set of input
data, in relation to what is considered the best achievable results.
mishap
an unplanned event or series of events resulting in death, injury, occupational illness, or damage
to or loss of equipment or property, or damage to the environment.
mission
the purpose and functions of the space system (sensors, transponders, boosters, experiments, etc.)
throughout its expected operational lifetime, and controlled reentry or disposal orbit time period.
A space system may have multiple missions (e.g., primary mission, ancillary mission, and safety
mission).
mission assurance
the program-wide identification, evaluation, and mitigation or control of all existing and
potential deficiencies that pose a threat to system safety or mission success, throughout the
product’s useful life and post-mission disposal.
NOTE: Deficiencies include damaging-threatening hazards, mission-impacting failures, and
system performance anomalies that result from unverified requirements, optimistic
assumptions, unplanned activities, ambiguous procedures, undesired environmental
conditions, latent physical faults, inappropriate corrective actions, and operator errors.
mission capability
This term encompasses the purpose and functions of the space system (sensors, transponders,
etc.) throughout its intended system mean mission duration (the expected life of the space
vehicle). (Ref. AFMAN 91-222 SUPL1).
26
mitigation
(1) a method that eliminates or reduces the consequences, likelihood, or effects of a hazard or
failure mode; (2) a hazard control.
modeling
act of producing a representation or simulation of one or more items.
non-credible failure mode or hazard
a failure mode or hazard with a probability of occurrence equal to or less than 1.0E-6, 0.000001,
or one in a million.
NOTE: In System Safety Engineering, the qualitative probability values of an improbable hazard
and a non-credible hazard are equivalent.
plan
a method for achieving an end.
practice
one or more activities that use specified inputs to develop specified work products for achieving
specified objectives (Ref. IEEE Standard 1624-2008).
process-based lesson learned
important information created, documented, and retrieved according to a process or procedure
descriptor.
product-based lesson learned
important information created, documented, and retrieved according to a system or device life
cycle specific functional or physical descriptor.
27
program
[1] the managed collection of an organization’s practices that is structured to ensure that the
customers’ requirements and product needs are satisfied (Ref. IEEE Standard 1624-2008); [2] a
defined set of managed processes conducing to an end under a single plan.
NOTE: A program does not have to consist of related, managed process. Compare with definition
of “system”.
process
a sequence of tasks, actions, or activities, including the transition criteria for progressing from
one to the next, that bring about a result (Ref. IEEE Standard 1624-2008).
NOTE: A process can be unmanaged or managed. An unmanaged or "free" process does not
have its inputs or outputs controlled. The rain and melted snow that replenishes a lake is
an example of an unmanaged process. A managed or "controlled" process has its inputs
and outputs controlled. An electrical power station is an example of a managed process.
quality
a measure of a part’s ability to meet the workmanship criteria of the manufacturer.
NOTE: Quality levels for parts used by some of the handbook methods are different from quality
of the parts. Quality levels are assigned based on the part source and level of screening
the part goes through. The concept of quality level comes from the belief that screening
improves part quality.
reliability
probability that an item will perform its intended function for a specified interval under stated
conditions.
residual risk
risk associated with significant failure modes or hazards for which there are no known control
measures, incomplete control measures, or no plans to control the failure mode or hazard.
28
root cause(s)
most fundamental reason(s) an event might or has occurred.
root cause analysis
a process for identifying the fundamental cause of an event or failure.
safety
freedom from those conditions that can cause death, injury, occupational illness, or damage to or
loss of equipment or property, or damage to the environment.
safety critical
a term applied to a condition, event, operation, process or item of whose proper recognition,
control, performance or tolerance is essential to safe system operation or use; e.g., safety critical
function, safety critical path, safety critical component.
specialty engineering
a subgroup of the engineering processes that make up the Mission Assurance Process
Note: Traditionally, this subgroup includes Reliability, Maintainability, PMP, Survivability, and
Supportability.
system
[1] a defined set of related processes.
[2] elements of a composite entity, at any level of complexity of personnel, procedures,
materials, tools, equipment, facilities, and software, that are used together in an intended
operational or support environment to perform a given task or achieve a specific purpose,
support, or mission requirement.
NOTE: A system that consists of one or more unmanaged processes is susceptible to becoming
“unbalanced” and changing over time (e.g., an ecological system). For a system to
maintain stability it must be “balanced” and consist only of managed processes.
29
system safety
the application of engineering management principles, criteria, and techniques to optimize all
aspects of safety within the constraints of operational effectiveness, time, and cost throughout all
phases of the system lifecycle (Ref. MIL-STD-882C).
systems engineering
An interdisciplinary approach encompassing the entire technical effort to evolve and verify an
integrated and life-cycle balance set of system product and process solutions that satisfy
customer needs. (Ref. MIL-STD-499B Draft).
tailoring
process by which the individual requirements (tasks, sections, paragraphs, words, phrases, or
sentences) of a standard are evaluated to determine the extent to which each requirement is most
suited for a specific system acquisition and the modification of these requirements, where
necessary, to ensure that each tailored document invokes only the minimum needs of the
customer.
timely
performance of a task, subtask, or effort when planning and execution results in the output being
provided with sufficient time for management, if need be, to identify and implement costeffective action.
EXAMPLE:
An action that avoids or minimizes schedule delays and cost increases.
validation
the act of determining that a product or process, as constituted, will fulfill its desired purpose
verification
the process of assuring that a product or process, as constituted, complies with the requirements
specified for it
