They serve as benchmarks that help track the development of skills and knowledge over time, allowing individuals and organizations to evaluate their effectiveness and adjust their strategies accordingly.
Lifetime value: Lifetime value, often abbreviated as LTV, is a metric that estimates the total revenue a business can expect from a customer over the entire duration of their relationship. This concept is crucial as it helps businesses understand how much they can invest in acquiring customers while still maintaining profitability. By focusing on LTV, companies can prioritize long-term relationships and customer satisfaction to maximize their revenue potential.
Minimum Viable Product: A Minimum Viable Product (MVP) is a basic version of a product that includes only the essential features needed to satisfy early adopters and gather feedback for future development. This approach allows businesses to test their ideas quickly and economically, enabling rapid adjustments based on user responses. By focusing on core functionalities, an MVP helps in reducing wasteful spending and resources while validating the market demand before investing heavily in full-scale development.
Pivot: A pivot is a strategic shift in business model or product development that allows an organization to test a new approach based on feedback and learning. It serves as a critical mechanism for adapting to market demands, optimizing offerings, or addressing shortcomings of the original concept, ultimately enhancing the chances of success in a competitive landscape.
Problem-Solution Fit: Problem-solution fit refers to the alignment between a specific problem faced by customers and the solution provided by a product or service. It emphasizes understanding the customer’s needs and ensuring that the proposed solution effectively addresses those needs. Achieving this fit is crucial in validating an idea before moving forward with product development and scaling, ultimately enhancing the chances of success in the marketplace.
Product-market fit: Product-market fit refers to the alignment between a product and the needs of the market, indicating that a product satisfies a strong demand from a specific customer segment. Achieving product-market fit means that a product is not only appealing to customers but also meets their needs effectively, leading to sustainable growth and customer loyalty. It's essential for businesses to validate their assumptions about customer needs and ensure that their offerings resonate well within their target market.

Scrum breaks projects into smaller, manageable pieces called sprints, allowing teams to deliver functional increments of a product regularly while promoting transparency and continuous improvement.
Steve Blank: Steve Blank is an American entrepreneur, author, and educator, recognized for his contributions to the development of the Lean Startup methodology and customer development principles. His approach emphasizes the importance of validating business ideas through direct customer feedback and iterative product development. This methodology encourages startups to minimize waste and optimize resources, aligning perfectly with bootstrapping techniques that focus on self-funding and resourcefulness.
Validated learning: Validated learning is the process of demonstrating through empirical evidence that a specific hypothesis about a product or business model is true. It connects closely to the iterative nature of developing products, allowing entrepreneurs to pivot or persevere based on what they learn from real customer feedback and data, rather than relying solely on assumptions or guesses.
Value Stream Mapping: Value stream mapping is a lean-management technique that helps visualize the flow of materials and information required to bring a product or service to the customer. By mapping out each step in the process, organizations can identify waste, inefficiencies, and opportunities for improvement, which aligns perfectly with lean startup principles aimed at maximizing value and minimizing waste.
Vanity metrics: Vanity metrics are measurements that may look impressive but do not provide meaningful insights into the performance or success of a business. These metrics often focus on numbers that boost self-esteem, such as total downloads or social media likes, rather than metrics that reflect actual growth or customer engagement. Understanding vanity metrics is crucial for businesses aiming to adopt lean startup principles, as they emphasize actionable metrics that drive real progress.
