Definition
Work in Process (WIP), also referred to as work in progress, represents goods that are in the stages of production but have not yet been completed. This includes items in various phases of assembly that are not ready for sale but are further along than raw materials. WIP is a key component in the inventory of manufacturing organizations and must be managed and valued accurately for both accounting and operational purposes.
Examples
- Automobile Manufacturing: In an automobile manufacturing plant, a partially assembled car that has received its frame, engine, and some electrical fittings but has not yet been fully assembled is classified as WIP.
- Construction Industry: In the construction sector, an ongoing building project that has not been completed yet is considered WIP.
- Textile Production: In textile mills, materials that have been spun into yarn but have not yet been woven into fabric and finished are deemed WIP.
