NPD

NPD is an acronym with multiple meanings depending on context. In clinical psychology, it refers to Narcissistic Personality Disorder, a mental health condition. In business, it stands for New Product Development, the process of creating and bringing a new product to market.

Narcissistic Personality Disorder (NPD) is a pervasive pattern of grandiosity, need for admiration, and lack of empathy that begins in early adulthood and occurs across settings. The DSM-5-TR criteria require five or more symptoms, such as a grandiose sense of self-importance; preoccupation with fantasies of unlimited success, power, brilliance, or beauty; belief of being special; need for excessive admiration; sense of entitlement; interpersonally exploitative behavior; lack of empathy; envy; and arrogant behaviors. The condition causes distress or impairment. Prevalence is estimated at about 1–6% of the population, more often diagnosed in men. Treatment centers on psychotherapy; medications may treat comorbid symptoms.

New Product Development (NPD) is the structured process of conceiving, designing, testing, and launching new products. Typical stages include idea generation, screening, concept development, business case, design and prototyping, testing, and market launch, followed by post-launch review. Many organizations use stage-gate processes, while others apply design thinking or agile methods to accelerate delivery.

Cross-functional teams from marketing, engineering, manufacturing, and finance work together to align customer needs with feasibility and business viability. Key risks include market misfit, cost overruns, and delays. Metrics such as time to market, development cost, return on investment, and post-launch performance measure success.
