Use when asked about the flywheel effect — small, continuous efforts compounding into significant momentum over time — as a strategic-growth model distinct from strategic-network-effects (which depends on user count specifically) and strategic-viral-effects (which depends on sharing specifically).
Use when asked about (operating) leverage effects — how fixed costs amplify the impact of sales changes on profitability, in either direction — as a financial-structure effect distinct from the growth-oriented strategic effects (network, platform, scale) elsewhere in this collection.
Use when asked about a competitive "moat" — a durable competitive advantage (brand, technology, user base, exclusive resources) that defends market position — as the umbrella concept several other strategic effects (strategic-network-effects, strategic-platform-effects, strategic-scale-effects) are specific sources of.
Use when asked about monopoly effects — the economic and social consequences of a market dominated by a single company (reduced innovation, pricing power, barriers to entry) — as the extreme, socially concerning endpoint several other strategic effects (network, platform, scale, moat) can lead toward.
Use when asked about network effects — a product or service becoming more valuable as more people use it (Metcalfe's Law), direct vs. indirect network effects — as one of several related strategic effects (see also strategic-platform-effects, strategic-viral-effects) that can create durable competitive advantage.
Use when asked about the platform effect — a platform's value increasing as more users AND third-party developers join and build on it — as a broader driver of, and complement to, strategic-network-effects specifically on multi-sided platforms.
Use when asked about scale effects — how a business's size affects its costs, revenues, and profitability through economies of scale, network effects, and learning effects — as an umbrella concept combining several distinct mechanisms.
Use when asked about threshold effects — a tipping point where crossing a critical level causes significant, often non-linear change (economies of scale, market penetration, technology adoption) — as a pattern underlying several other strategic effects in this collection.
Use when asked about viral effects — a product or service spreading rapidly through word-of-mouth or social sharing — as a growth mechanism distinct from strategic-network-effects (value from usage) and strategic-flywheel-effects (compounding operational effort).
