Process maturity means that whatever an organisation is doing, it is done in a well-documented way, and everyone knows what is expected of them and performs accordingly. A process is capable if it satisfies its specified product quality, service quality, and process performance objectives. A capable process consistently produces output that is within specifications. Execution of capable process always gives predictable results. Process maturity levels classify organisations according to their ability to control their various processes. Process capability levels classify the performances of (some) processes of a certain process area done by an organisation, organisational department, or project. Process maturity models define reference and assessment schemes for maturity resp. capability levels in detail.
Process maturity and capability can have two different representations: staged or continuous. The differences between the structures are subtle but significant. The staged representation uses so-called maturity levels to characterise the overall state of the organisation's processes relative to the model as a whole. Instead, the continuous representation of uses so-called capability levels to characterise the state of the organisation's processes relative to an individual process area. Process capability relates to the performances of (some) processes of a certain process area.
The IDEAL model realises a methodical infrastructure framework to guide organisations in planning and implementing effective process improvement programs for CMMI and alike initiatives. It is a process-improvement and defect-reduction methodology serving as the founding strategy employed by SEI in delivering many of their services.
Why is playing so important? — Because this can make us smarter at any age! But play is anything but trivial. It is a biological drive as integral to our health as sleep or nutrition. Play is essential to develop social skills and adult problem-solving skills. We are designed by nature to flourish through play. In the following TedX video, Dr. Stuart Brown, founder of the US National Institute for Play, illustrates why playing is essential.
A Process Reference Model describes for a certain application domain a set of processes. Each process is described by its purpose and the associated process outcomes (i.e. work products). Process Reference Models are always related to a Process Assessment Model.
Institutionalisation is an important concept in process improvement. When mentioned in the generic goal and generic practice descriptions, institutionalization implies that the process is ingrained in the way the work is performed and there is a company-wide commitment and consistency to performing the process.
A Process Assessment Model (PAM) relates to one or more Process Reference Models. A PAM holds all details (so called indicators) to determine process maturity. It is aligned in two dimensions: Process and Maturity level.
In SCAMPI appraisals, the FIDO Database manages all appraisal data, reports, and presentations and is highly-rated by appraisal teams. With a FIDO Database, teams spend less time organising data and have more time available to analyze the data and prepare findings.
The Appraisal Requirements for CMMI (ARC) defines the requirements considered essential to appraisal methods intended for use with Capability Maturity Model Integration CMMI models. In addition, a set of appraisal classes is defined, based on typical applications of appraisal methods. These classes are intended primarily for developers of appraisal methods to use with CMMI capability models in the context of the CMMI Product Suite.
The Standard CMMI Appraisal Method for Process Improvement (SCAMPI) is designed to provide benchmark quality ratings relative to Capability Maturity Model Integration (CMMI) models. It is applicable to a wide range of appraisal usage modes, including both internal process improvement and external capability determinations. SCAMPI satisfies all of the Appraisal Requirements for CMMI requirements for a Class A appraisal method and supports the conduct of ISO/IEC 15504 assessments as well.
