This chapter shows how blockchain technology can create real value for companies, especially small- and medium-sized enterprises (SMEs). It first introduces key ideas, including public and permissioned blockchains, consensus methods, and smart contracts in clear, non-technical language. Next, it gives a step-by-step plan to analyse business processes, map stakeholders, and run a simple utility analysis to see which process is the best place to start. The study then explains technical points such as system architecture, data storage (on-chain versus off-chain), and links to current IT systems. A special section presents Decentralised Autonomous Organisations (DAOs) as a new way to manage joint work without middlemen. Throughout, the author stresses that blockchain is not a goal itself, and that it helps only when it cuts costs, saves time, or opens new business options. The framework offered here helps managers judge when and when not to use blockchain in practice.
