The Four Stages of the Product Life Cycle (historical version)

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 pricing strategy where a dominant firm sets prices for goods or services at an extremely low level, potentially below cost, to eliminate or discipline competitors. Once rivals are driven out of the market, the firm can raise prices to monopoly levels to recoup its losses. This practice is a method to create significant barriers to entry for new market participants.

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.

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.

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.

The Ideal Final Result (IFR) is a core concept in TRIZ that defines the ultimate, perfect solution to a problem, independent of current constraints or resources. It is typically formulated as "the system (or element) itself performs the required function without its own existence." This mental tool helps problem-solvers overcome psychological inertia and focus on function rather than form.

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.

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.
