Description
When to Apply
Work In Progress (WIP)
– Refers to the materials and items involved in the production process but not yet completed. It’s a stage in the inventory that is in between raw materials and finished goods. WIP requires effective management to ensure that production is efficient and that excess costs due to overstocking or delays are minimized.
– Critical in manufacturing and production settings where managing the flow and efficiency of production processes is essential to optimize costs and production times.
Lean Manufacturing
– A systematic method for waste minimization within a manufacturing system without sacrificing productivity. Lean focuses on enhancing process speed and quality by reducing waste and non-value-added activities.
– Applied in manufacturing processes to improve efficiency, reduce waste, and increase productivity.
Just-In-Time (JIT) Inventory
– A management strategy that aligns raw-material orders from suppliers directly with production schedules. It is used to increase efficiency and decrease waste by receiving goods only as they are needed in the production process, thus reducing WIP levels.
– Suitable for organizations aiming to reduce inventory costs, enhance operational efficiency, and improve cash flow.
Kanban System
– A lean method to manage and improve work across human systems. This approach aims to manage work by balancing demands with available capacity and improving the handling of system-level bottlenecks. Kanban helps regulate the flow of goods inside the factory and from external suppliers.
– Utilized in production and service environments where work needs to be visually managed to ensure continuous flow and on-time delivery.
Total Quality Management (TQM)
– A company-wide philosophy that focuses on continuously improving the quality of all processes, products, and services by involving all employees from upper management to assembly line workers.
– Implemented across all areas of a company to embed quality assurance and continuous improvement in every product and process.
Capacity Planning
– The process of determining the production capacity needed by an organization to meet changing demands for its products. Capacity planning is closely tied to managing WIP to ensure that production capabilities can meet customer demand without excessive delays or costs.
– Essential in operations management for aligning investment in production capacity with market demands and ensuring efficient operation without overcapacity.
Supply Chain Management (SCM)
– The management of the flow of goods and services, involving the movement and storage of raw materials, of work-in-process inventory, and of finished goods from point of origin to point of consumption.
– Critical in optimizing operational efficiencies and ensuring the effective flow of goods, services, and information across all parts of the supply chain.
Cycle Time
– The total time from the beginning to the end of a process, as defined by the customer. This includes the process time and any time during which the WIP is waiting to be processed.
– Monitored in settings where reducing the time it takes to produce an item or service can lead to significant improvements in productivity and customer satisfaction.
Bottleneck Analysis
– The process of identifying bottlenecks that slow down production processes and developing strategies to resolve them. Bottlenecks in a production line often lead to increased WIP as work backs up behind the slow point.
– Employed to identify and mitigate delays in production processes, enhancing overall efficiency and reducing WIP levels.
Inventory Turnover Ratio
– A measure of how many times inventory is sold or used in a time period. A higher turnover ratio indicates efficiency in managing inventory, including WIP, as it suggests a company is better at converting its inventory into sales.
– Used to assess operational efficiency and inventory management practices, aiming to optimize the balance between having enough inventory to meet customer demands and minimizing holding costs.

The Agile methodology has been primarily thought of for software development (and other business disciplines have also adopted it). Lean thinking is a process improvement technique where teams prioritize the value streams to improve it continuously. Both methodologies look at the customer as the key driver to improvement and waste reduction. Both methodologies look at improvement as something continuous.
A startup company is a high-tech business that tries to build a scalable business model in tech-driven industries. A startup company usually follows a lean methodology, where continuous innovation, driven by built-in viral loops is the rule. Thus, driving growth and building network effects as a consequence of this strategy.
As pointed out by Eric Ries, a minimum viable product is that version of a new product which allows a team to collect the maximum amount of validated learning about customers with the least effort through a cycle of build, measure, learn; that is the foundation of the lean startup methodology.
Kanban is a lean manufacturing framework first developed by Toyota in the late 1940s. The Kanban framework is a means of visualizing work as it moves through identifying potential bottlenecks. It does that through a process called just-in-time (JIT) manufacturing to optimize engineering processes, speed up manufacturing products, and improve the go-to-market strategy.

RAD was first introduced by author and consultant James Martin in 1991. Martin recognized and then took advantage of the endless malleability of software in designing development models. Rapid Application Development (RAD) is a methodology focusing on delivering rapidly through continuous feedback and frequent iterations.
Retrospective analyses are held after a project to determine what worked well and what did not. They are also conducted at the end of an iteration in Agile project management. Agile practitioners call these meetings retrospectives or retros. They are an effective way to check the pulse of a project team, reflect on the work performed to date, and reach a consensus on how to tackle the next sprint cycle. These are the five stages of a retrospective analysis for effective Agile project management: set the stage, gather the data, generate insights, decide on the next steps, and close the retrospective.

Scrum anti-patterns describe any attractive, easy-to-implement solution that ultimately makes a problem worse. Therefore, these are the practice not to follow to prevent issues from emerging. Some classic examples of scrum anti-patterns comprise absent product owners, pre-assigned tickets (making individuals work in isolation), and discounting retrospectives (where review meetings are not useful to really make improvements).
Scrum at Scale (Scrum@Scale) is a framework that Scrum teams use to address complex problems and deliver high-value products. Scrum at Scale was created through a joint venture between the Scrum Alliance and Scrum Inc. The joint venture was overseen by Jeff Sutherland, a co-creator of Scrum and one of the principal authors of the Agile Manifesto.
Six Sigma is a data-driven approach and methodology for eliminating errors or defects in a product, service, or process. Six Sigma was developed by Motorola as a management approach based on quality fundamentals in the early 1980s. A decade later, it was popularized by General Electric who estimated that the methodology saved them $12 billion in the first five years of operation.
Stretch objectives describe any task an agile team plans to complete without expressly committing to do so. Teams incorporate stretch objectives during a Sprint or Program Increment (PI) as part of Scaled Agile. They are used when the agile team is unsure of its capacity to attain an objective. Therefore, stretch objectives are instead outcomes that, while extremely desirable, are not the difference between the success or failure of each sprint.
