Gantt Chart

The Critical Path Method (sometimes referred as CPM, confusing in many domains) is a methodology for scheduling project activities. It identifies the longest stretch of dependent tasks (the 'critical path') and measures the time required to complete them from start to finish. Any delay in a task on the critical path directly impacts the project's completion date -targeted parameter here is date, not cost, nor quality, nor resources, although none of these are independent-. It helps consequently in resource allocation and schedule optimization.

A foundational model in marketing, the 4Ps framework classifies the key elements a business uses to promote its brand or product. It consists of Product (the item or service), Price (the cost to the consumer), Place (where it's sold), and Promotion (the advertising and sales activities). These four variables are controlled by the company to influence consumer demand.

Kaizen is a Japanese term meaning "change for the better" or "continuous improvement." It is a core philosophy of lean manufacturing that focuses on making small, ongoing, positive changes to improve processes and eliminate waste. Kaizen involves all employees, from senior management to assembly line workers, fostering a culture where everyone is empowered to suggest and implement improvements.

A "blockbuster drug" is a pharmaceutical product that generates more than $1 billion in annual sales for its manufacturer. This business model has historically driven the pharmaceutical industry, focusing research and development (R&D) on common, chronic conditions to maximize patent-protected revenue. This revenue funds further R&D for new drugs, creating a cycle of innovation and high profits.

Gemba (現場) is the Japanese term for 'the actual place.' In management, it refers to the place where value is created, such as the factory floor. Gemba Kaizen is the principle of going to the Gemba to observe the process, engage with workers, and identify opportunities for improvement directly at the source, rather than from a remote office.

Six Sigma implementation involves a hierarchy of certified professionals, designated by colored "belts" similar to martial arts. Key roles include Master Black Belts, who mentor and train; Black Belts, who lead complex improvement projects; Green Belts, who lead smaller projects as part of their regular duties; and Yellow Belts, who have basic training and participate on project teams.

The term 'upcycling' was first coined in 1994 by German engineer Reiner Pilz in an interview with journalist Thornton Kay. Pilz contrasted it with 'down-cycling,' where materials are converted into something of lesser quality. He described upcycling as the process where old products are given more value, not less, highlighting the need for a new perspective on waste materials.

The marketing concept is a business philosophy holding that achieving organizational goals depends on knowing the needs and wants of target markets and delivering the desired satisfactions more effectively and efficiently than competitors. It represents a shift from a product-centric ("make and sell") approach to a customer-centric ("sense and respond") one, placing the customer at the core of all business decisions.

A Work Breakdown Structure (sometimes abbreviated WBS) is a key project deliverable that organizes the team's work into manageable sections. It is a hierarchical and incremental decomposition of the project into phases, deliverables, and work packages. The WBS is a tree structure that shows a subdivision of effort required to achieve an objective, such as a program, project, or contract.

The Project Management Triangle, also known as the Triple Constraint or Iron Triangle, is a model of the constraints inherent in managing a project. It states that the quality of work is constrained by the project's budget (cost), deadlines (time), and scope. A change in one constraint necessitates changes in the others to maintain quality and equilibrium.

5S is a workplace organization method that uses a list of five Japanese words: Seiri (Sort), Seiton (Set in Order), Seisō (Shine), Seiketsu (Standardize), and Shitsuke (Sustain). This system aims to improve efficiency and eliminate waste by organizing a workspace for effectiveness. It is a foundational component of Kaizen and lean manufacturing, creating the stable environment necessary for improvement.

Relationship marketing is a strategic approach that shifts the focus from individual transactions to building long-term customer loyalty and engagement. It emphasizes customer retention, satisfaction, and lifetime value over short-term sales goals. Key tactics include customer relationship management (CRM) systems, loyalty programs, and personalized communication, aiming to create a strong, emotional connection between the brand and the customer.

Disintermediation is the economic process of removing intermediaries from a supply chain, thereby connecting producers directly with consumers. In the DTC context, this means bypassing traditional wholesalers, distributors, and brick-and-mortar retailers. This structural change allows brands to capture profit margins that would otherwise go to middlemen, while also gaining direct control over their product's journey and presentation to the market.
