Engineering analysis involves the application of scientific/mathematical analytic principles and processes to reveal the properties and state of a system, device or mechanism under study.
Engineering analysis is decompositional: it proceeds by separating the
engineering design into the
mechanisms of operation or failure, analyzing or estimating each component of the operation or
failure mechanism in isolation, and re-combining the components according to basic physical principles and
natural laws
Natural law ( la, ius naturale, ''lex naturalis'') is a system of law based on a close observation of human nature, and based on values intrinsic to human nature that can be deduced and applied independently of positive law (the express enacted ...

Applied/engineering mathematical analysis
Engineering analysis and applied analysis are synonym terms for
mathematical analysis
Analysis is the branch of mathematics dealing with continuous functions, limit (mathematics), limits, and related theories, such as Derivative, differentiation, Integral, integration, measure (mathematics), measure, infinite sequences, series (m ...

calculus
Calculus, originally called infinitesimal calculus or "the calculus of infinitesimals", is the mathematical study of continuous change, in the same way that geometry is the study of shape, and algebra is the study of generalizations of arithm ...

physics
Physics is the natural science that studies matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. "Physical science is that department of knowledge which r ...

Remote systems
Engineering analysis is the primary method for predicting and handling issues with
remote systems such as
satellites and
rovers. Engineering analysis for remote systems must be ongoing since the health and safety of the remote system can only be affected remotely (and because any failure could have fatal consequences).
The capabilities of engineering analysis therefore must incorporate
trending as well as analysis. Trending should be
proactive
Proactivity or proactive behavior refers to self-initiated behavior that endeavours to solve a problem before it has occurred. Proactive behavior involves acting in advance of a future situation, rather than reacting. It refers to taking control o ...

predictive, comprehensive and automated. Analysis must be reactive, investigative, targeted and hands-on. Together trending and analysis allow operators to both predict potential situations and identify
anomalous events that threaten a remote system.
