Work In Progress (WIP), also known as work in process, refers to partially finished goods in the manufacturing cycle or any investments in development stages within a business process. WIP accounts for the raw materials, labor, and overhead costs invested in products that are not yet completed. This term is also used in project management to describe tasks or projects that are still under development.
Historical Context
The concept of work in progress has been integral to manufacturing and project management throughout history. Since the industrial revolution, the tracking of WIP has been essential for optimizing production efficiency and inventory management. This practice has evolved with advancements in technology, enhancing real-time tracking and lean manufacturing methodologies.
Types/Categories
- Manufacturing WIP: Includes raw materials, labor costs, and overhead allocated to goods not yet finished.
- Project Management WIP: Refers to ongoing projects or tasks that are still under development.
- Financial Investments WIP: Involves investments still in progress, such as real estate under construction or stocks yet to reach full potential.
Key Events
- Industrial Revolution (1760-1840): Shift from hand production to machines, leading to increased focus on managing WIP efficiently.
- Toyota Production System (1940s): Development of lean manufacturing techniques, emphasizing reduction of WIP.
- Modern ERP Systems: Integration of software solutions to manage and track WIP in real-time.
Detailed Explanations
Manufacturing WIP
Work in Progress in manufacturing consists of raw materials, labor, and overhead costs applied to partially finished goods.
Project Management WIP
In project management, WIP includes all tasks that are currently in progress but not completed. Effective management ensures that projects move forward smoothly without bottlenecks.
Financial Investments WIP
Refers to investments that are still in development, such as real estate projects under construction, startup ventures, or stocks in emerging markets.

Importance and Applicability
- Efficiency: Helps in identifying bottlenecks and inefficiencies in production.
- Financial Analysis: Provides insight into the allocation of resources and helps in cost control.
- Project Planning: Enables better tracking and management of ongoing tasks and projects.
Examples
- Manufacturing: Automotive assembly lines where parts are in various stages of assembly.
- Construction: Buildings under construction with resources allocated but not yet completed.
- Software Development: Applications in different development stages awaiting completion.
Considerations
- Inventory Management: Keeping WIP at optimal levels to avoid excess carrying costs.
- Resource Allocation: Ensuring that resources are adequately distributed without overburdening specific stages.
- Monitoring and Control: Regular tracking to prevent project delays and cost overruns.
Related Terms with Definitions
- Raw Materials: Basic materials from which products are made.
- Finished Goods: Completed products ready for sale.
- Lean Manufacturing: A systematic method for waste minimization without sacrificing productivity.
Comparisons
- WIP vs. Finished Goods: WIP includes partially completed items, whereas finished goods are fully completed and ready for sale.
- WIP vs. Raw Materials: WIP includes work done on raw materials, while raw materials are untouched initial inputs.
Interesting Facts
- The concept of WIP is closely linked to the Japanese principle of Kaizen, which focuses on continuous improvement in processes.
Inspirational Stories
Toyota’s success with its lean manufacturing approach, reducing WIP and increasing efficiency, stands as a hallmark of effective WIP management.
Famous Quotes
“Great things are not done by impulse, but by a series of small things brought together.” – Vincent Van Gogh
Proverbs and Clichés
- Proverb: “A stitch in time saves nine.”
- Cliché: “Rome wasn’t built in a day.”
Expressions
- “In the pipeline”: Refers to tasks or projects that are currently in progress.
Jargon and Slang
- “Pipeline Fillers”: Uncompleted tasks filling up the project pipeline.
- “Bottlenecking”: Slowdown in production due to inefficiencies at specific WIP stages.
FAQs
Q1: How is WIP different from finished goods inventory? A1: WIP includes items in the process of manufacturing, whereas finished goods inventory includes items ready for sale.
Q2: How can WIP be optimized? A2: By implementing lean manufacturing techniques and regular monitoring.

Summary
Work In Progress (WIP) is a crucial concept in manufacturing, project management, and investment, representing partially finished goods and ongoing projects. Effective WIP management optimizes production efficiency, resource allocation, and financial performance. Techniques such as lean manufacturing can significantly reduce WIP, leading to better organizational productivity and success.
