Editing Product lifecycle (section)

==Introduction to development process==
The core of PLM (product lifecycle management) is the creation and central management of all product data and the technology used to access this information and knowledge. PLM as a discipline emerged from tools such as [[Computer-aided design|CAD]], [[Computer-aided manufacturing|CAM]] and [[product data management|PDM]], but can be viewed as the integration of these tools with methods, people and the processes through all stages of a product's life.<ref>{{cite journal |last1=Kopei |first1=Volodymyr |last2=Onysko |first2=Oleh |last3=Barz |first3=Cristian |last4=Dašić |first4=Predrag |last5=Panchuk |first5=Vitalii |date=February 2023 |title=Designing a Multi-Agent PLM System for Threaded Connections Using the Principle of Isomorphism of Regularities of Complex Systems |journal=Machines |volume=11 |issue=2 |pages=263 |doi=10.3390/machines11020263 |doi-access=free |url=https://www.preprints.org/manuscript/202301.0048/v1/download }}</ref><ref>{{cite magazine |last=Teresko |first=John |title=The PLM Revolution |magazine=IndustryWeek |date=21 December 2004 |url= http://www.industryweek.com/companies-amp-executives/plm-revolution |access-date=26 September 2012}}</ref> It is not just about software technology but is also a business strategy.<ref>{{cite magazine |last=Stackpole |first=Beth |title=There's a New App in Town |magazine=CIO Magazine |date=11 June 2003 |url=http://www.cio.com.au/article/17806/there_new_app_town/ |access-date=25 February 2012 |archive-date=15 September 2019 |archive-url=https://web.archive.org/web/20190915213753/https://www.cio.com.au/article/17806/there_new_app_town/ |url-status=dead }}</ref>

For simplicity, the stages described are shown in a traditional sequential engineering workflow.
The exact order of events and tasks will vary according to the product and industry in question but the main processes are:<ref>{{cite web|last=Gould |first=Lawrence |title=Additional ABCs About PLM |publisher=Automotive Design and Production |date=12 January 2005 |url= http://www.autofieldguide.com/articles/120506.html |access-date=25 February 2012 |archive-url= https://web.archive.org/web/20100607073217/http://www.autofieldguide.com/articles/120506.html |archive-date=7 June 2010 |url-status=dead}}</ref>
*Conceive
**[[Specification]]
**Concept design
*Design
**Detailed design
**Validation and analysis (simulation)
**Tool design
*Realise
**Plan manufacturing
**Manufacture
**Build/Assemble
**Test ([[quality control]])
*Service
**Sell and deliver
**Use
**Maintain and support
**Dispose

The major key point events are:
*Order
*Idea
*[[Kickoff meeting|Kickoff]]
*Design freeze
*Launch

The reality is however more complex, people and departments cannot perform their tasks in isolation and one activity cannot simply finish, and the next activity start. Design is an iterative process, often designs need to be modified due to manufacturing constraints or conflicting requirements. Whether a customer order fits into the timeline depends on the industry type and whether the products are, for example, built to order, engineered to order, or assembled to order.
