34-433: The V-model summarizes the main steps to be taken in conjunction with the corresponding deliverables within computerized system validation framework, or project life cycle development. It describes the activities to be performed and the results that have to be produced during product development. The left side of the "V" represents the decomposition of requirements, and the creation of system specifications. The right side of

68-484: A mindset that keeps the project aligned with the PRINCE2 methodology. If a project does not adhere to these principles, it is not being managed using PRINCE2. Not every aspect of PRINCE2 will be applicable to every project, thus every process has a note on scalability . This provides guidance to the project manager (and others involved in the project) as to how much of the process to apply. The positive aspect of this

102-530: A project can be blamed on inappropriate application of PRINCE2 rather than on PRINCE2 itself. The experiences of the Blair administration in the UK between 1997 and 2007 (and of subsequent UK governments) arguably undermine PRINCE2's claim to be "best practice", given the string of high-profile failed IT projects charged to the taxpayer during that time, and the controversy surrounding the financial relationship between

136-423: A project's products are of the required standard (i.e. meet defined quality criteria). This takes place in a quality review meeting, which identifies errors in the product. The quality review meeting will not attempt to solve the problems it identifies. The meeting brings together people who have an interest in the project's outputs (or products) and people on the project team able to address issues identified. Below

170-456: Is a list of all the editions of PRINCE2. As of 1 January 2020, "PRINCE2 2017" was renamed "PRINCE2 6th Edition". Also, the previous edition, "PRINCE2 2009" was renamed "PRINCE2 5th Edition". There were no other changes except the name of the brand. The reason for the name change was to "ensure the format of the name is aligned with that used by other frameworks within the project management industry". As list of all versions of PRINCE2 are printed in

204-454: Is a narrower systems development lifecycle model, but far more detailed and more rigorous than most UK practitioners and testers would understand by the V-model. It is sometimes said that validation can be expressed by the query "Are you building the right thing?" and verification by "Are you building it right?" In practice, the usage of these terms varies. The PMBOK guide , also adopted by

238-525: Is adopted in many countries worldwide, including the UK, Western European countries, and Australia. PRINCE2 training is available in many languages. PRINCE2 was developed as a UK government standard for information systems projects. In July 2013, ownership of the rights to PRINCE2 were transferred from HM Cabinet Office to AXELOS Ltd , a joint venture by the Cabinet Office and Capita , with 49% and 51% stakes respectively. In 2021, PRINCE2

272-483: Is always against the requirements (technical terms) and validation is always against the real world or the user's needs. The aerospace standard RTCA DO-178B states that requirements are validated—confirmed to be true—and the end product is verified to ensure it satisfies those requirements. Validation can be expressed with the query "Are you building the right thing?" and verification with "Are you building it right?" There are three general types of V-model. "V-Modell"

306-473: Is done unnecessarily and everything that is necessary is accomplished. The specification stream mainly consists of: The testing stream generally consists of: The development stream can consist (depending on the system type and the development scope) of customization, configuration or coding. The V-model is used to regulate the software development process within the German federal administration. Nowadays it

340-464: Is now a de facto standard for project management in many UK government departments and across the United Nations system . There have been three major revisions of PRINCE2 since its launch in 1996: "PRINCE2:2009 Refresh" in 2009, and "PRINCE2 2017 Update" in 2017. The justification for the 2017 update was the evolution in practical business practices and feedback from PRINCE2 practitioners in

374-519: Is still the standard for German federal administration and defense projects, as well as software developers within the region. The concept of the V-model was developed simultaneously, but independently, in Germany and in the United States in the late 1980s: It has now found widespread application in commercial as well as defense programs. Its primary use is in project management and throughout

408-505: Is that PRINCE2 can be tailored to the needs of a particular project. The negative aspect is that many of the essential elements of PRINCE2 can be omitted sometimes resulting in a PINO project – PRINCE in Name Only The 7th edition of PRINCE2 introduced a major new aspect to the method - the role of people. The purpose of a project is to deliver change, which will affect the people who perform business as usual (BAU) activities. How well

442-427: Is the official project management method of the German government. It is roughly equivalent to PRINCE2 , but more directly relevant to software development. The key attribute of using a "V" representation was to require proof that the products from the left-side of the V were acceptable by the appropriate test and integration organization implementing the right-side of the V. Throughout the testing community worldwide,

476-681: Is the process of testing/validating/qualifying a regulated (e.g., US FDA 21 CFR Part 11 ) computerized system to ensure that it does exactly what it is designed to do in a consistent and reproducible manner that is as safe, secure and reliable as paper-based records. This is widely used in the Pharmaceutical, Life Sciences and BioTech industries and is a cousin of Software Testing but with a more formal and documented approach. The validation process begins with validation planning, system requirements definition, testing and verification activities, and validation reporting. The system lifecycle then enters

510-545: The C CTA E nvironment". PRINCE was renamed in a civil service competition as an acronym for " PR ojects IN C ontrolled E nvironments". PRINCE2 is the second edition of the earlier PRINCE method which was initially announced and developed in 1989 by the Central Computer and Telecommunications Agency (CCTA), a UK government support agency. PRINCE2 was released in 1996 as a generic project management method. Since then, PRINCE2 became increasingly popular and

544-563: The IEEE as a standard (jointly maintained by INCOSE, the Systems engineering Research Council SERC, and IEEE Computer Society) defines them as follows in its 4th edition: The V-model provides guidance for the planning and realization of projects. The following objectives are intended to be achieved by a project execution: The systems engineering process (SEP) provides a path for improving the cost-effectiveness of complex systems as experienced by

578-404: The "V" represents an integration of parts and their validation. However, requirements need to be validated first against the higher level requirements or user needs. Furthermore, there is also something as validation of system models. This can partially be done on the left side also. To claim that validation only occurs on the right side may not be correct. The easiest way is to say that verification

612-467: The Blair government and PRINCE2's co-owners Capita . PRINCE2's training material addresses these failures, blaming them on inappropriate tailoring of PRINCE2 to the project environment, and advocating for more PRINCE2 training for government project managers to solve the problem. Project Management Professional (PMP) from Project Management Institute may be seen as a competitor of PRINCE2. In general,

646-521: The UK, Australia prefer PRINCE2, and the US and American countries prefer PMP. Asia, Africa and the Middle East area have no strong preference for PMP or PRINCE2. The important thing is that PMP (PMBOK) can be used with PRINCE2. PRINCE2 and PMP acknowledge each other's existence in their advertising material and attempt to position themselves as complementary products – PRINCE2 as a "methodology" and PMP as

680-496: The V-model is publicly available many companies also use it. In project management it is a method comparable to PRINCE2 and describes methods for project management as well as methods for system development . The V-model, while rigid in process, can be very flexible in application, especially as it pertains to the scope outside of the realm of the System Development Lifecycle normal parameters. These are

714-669: The V-model is widely seen as a vaguer illustrative depiction of the software development process as described in the International Software Testing Qualifications Board Foundation Syllabus for software testers. There is no single definition of this model, which is more directly covered in the alternative article on the V-Model (software development) . The US also has a government standard V-model which dates back about 20 years like its German counterpart. Its scope

748-516: The actual project environment. More recently, in 2023 AXELOS launched PRINCE2 7 - the 7th edition - which is described below. These aspects are also called tolerances or performance goals . Tolerances define the delegated levels of authority which are set by a higher level of management to a lower level. The management level responsible must manage within the tolerances provided only as long as they are not forecast to be exceeded. Otherwise they are deemed to be an exception which requires escalating to

782-464: The advantages V-model offers in front of other systems development models: The following aspects are not covered by the V-model, they must be regulated in addition, or the V-model must be adapted accordingly: Computerized system validation Computerized system validation ( CSV ) (Computerised system validation in European countries, and usually referred to as "Computer Systems Validation")

816-551: The advertised benefits of PRINCE2 are: increased quality of the finished products, efficient control of resources, avoidance of either "heroic" (under-regulated) or "mechanistic" (over-regulated) working, and increased confidence among the project team. PRINCE2 is sometimes considered inappropriate for small projects or where requirements are expected to change, due to the work required in creating and maintaining documents, logs and lists. The deliverable structure may also lead to focus on producing deliverables for their own sake, to "tick

850-479: The boxes" rather than do more useful work. The general response of PRINCE2's authors to criticism has been to point out that the methodology is scalable and can be tailored to suit the specific requirements and constraints of the project and the environment. This strong emphasis on tailoring has led some users to complain that PRINCE2 is unfalsifiable , i.e. it is impossible to tell whether PRINCE2 "works" or constitutes "best practice" if any problems encountered with

884-430: The cover of the PRINCE2 manual: (*nth names added for other editions in order for context, but they were not referred to these names originally. However, they are referenced as such in the PRINCE2 manual cover page.) PRINCE2 provides a method for managing projects within a clearly defined framework, but project management is a complex discipline and using such a framework is no guarantee of a successful project. Some of

918-484: The intended use of a computer system application. System requirements are gathered and documented in the system definition phase. System definition artifacts that reflect these requirements can include, but are not limited to, the following: PRINCE2 PRINCE2 ( PRojects IN Controlled Environments ) is a structured project management method and practitioner certification programme. PRINCE2 emphasises dividing projects into manageable and controllable stages. It

952-461: The management level which delegated them. This way of managing is known as 'management by exception' and is one of the principles of PRINCE2. By managing in this way, it saves the time of senior management. In some organisations tolerances can be key performance indicators (KPIs). In the following table project level tolerances are summarised: PRINCE2 is based on seven principles and these cannot be tailored. The PRINCE2 principles can be described as

986-515: The operational phase and continues until system retirement and retention of system data based on regulatory rules. Similarly, The Rules Governing Medicinal Products in the European Union, Volume 4, Annex 11: Computerised Systems applies to all forms of computerized systems used as part of a GMP regulated activities and defines Computer System Validation Elements Documented system requirements are required for CSV as they clearly stipulate

1020-424: The project delivers the change, depends on the capabilities of the project team, the strength of the relationships between them, and the people impacted by the change. For these reasons, PRINCE2 recommends that projects must incorporate change management to be able to successfully implement the change into the organization. The management products described by PRINCE2 are only used for the "high-level" management of

1054-466: The project lifecycle. One fundamental characteristic of the US V-model is that time and maturity move from left to right and one cannot move back in time. All iteration is along a vertical line to higher or lower levels in the system hierarchy, as shown in the figure. This has proven to be an important aspect of the model. The expansion of the model to a dual-Vee concept is treated in reference. As

1088-436: The project. Within its tasks , task managers must still decide on their own project management framework. Some suggestions given in the PRINCE2 manual are product based planning , change control , quality review technique, Kanban boards , Gantt charts , PERT charts and critical path analysis. PRINCE2 can also be used to manage projects that use agile software development methods. The quality review technique ensures

1122-858: The system owner over the entire life of the system, from conception to retirement. It involves early and comprehensive identification of goals, a concept of operations that describes user needs and the operating environment, thorough and testable system requirements, detailed design, implementation, rigorous acceptance testing of the implemented system to ensure it meets the stated requirements (system verification), measuring its effectiveness in addressing goals (system validation), on-going operation and maintenance, system upgrades over time, and eventual retirement. The process emphasizes requirements-driven design and testing. All design elements and acceptance tests must be traceable to one or more system requirements and every requirement must be addressed by at least one design element and acceptance test. Such rigor ensures nothing

1156-443: Was transferred to PeopleCert during their acquisition of AXELOS. PRINCE was derived from an earlier method called PROMPT II (Project Resource Organisation Management Planning Techniques). In 1989 the Central Computer and Telecommunications Agency (CCTA) adopted a version of PROMPT II as a UK Government standard for information systems (IT) project management. They gave it the name 'PRINCE', which originally stood for " PR OMPT II IN
