Informally, EVM is a measure of how far the points are from the ideal locations. Noise, distortion, spurious signals, and phase noise all degrade EVM, and therefore EVM provides a comprehensive measure of the quality of the radio receiver or transmitter for use in digital communications.
For example, it may be impossible to plan certain research projects far in advance, because research itself uncovers some opportunities (research paths) and actively eliminates others. However, another school of thought holds that all work can be planned, even if in weekly timeboxes or other short increments .
The IMP is expanded to a time-based IMS to produce a networked and multi-layered schedule showing all detailed tasks required to accomplish the work effort contained in the IMP. The IMS flows directly from the IMP and supplements it with additional levels of detail——both then form the foundations to implement an Earned Value Management System.
For example, the XP requirements management approach, which relies on oral communication, was evaluated as not compliant with CMMI. CMMI can be appraised using two different approaches: staged and continuous. The staged approach yields appraisal results as one of five maturity levels. The continuous approach yields one of four capability levels.
Earned value management (EVM) is a project management technique for measuring project progress in an objective manner, with a combination of measuring scope, schedule, and cost in a single integrated system. Enterprise modeling is the process of understanding an enterprise business and improving its performance through creation of enterprise ...

Event sampling methodology (ESM) refers to a diary study.ESM is also known as ecological momentary assessment (EMA) or experience sampling methodology.ESM includes sampling methods that allow researchers to study ongoing experiences and events by taking assessments one or more times per day per participant (n=1) in the naturally occurring social environment.
Linear errors-in-variables models were studied first, probably because linear models were so widely used and they are easier than non-linear ones. Unlike standard least squares regression (OLS), extending errors in variables regression (EiV) from the simple to the multivariable case is not straightforward, unless one treats all variables in the same way i.e. assume equal reliability.
