What is PPM?

PPM can refer to several different technologies, including: 1. **Parts Per Million (PPM):** This is a unit of measurement for concentration, often used to express the amount of a substance in a larger mixture. For example, PPM can indicate the concentration of a pollutant in air or water. 2. **Pulse-Position Modulation (PPM):** A form of signal modulation where the amplitude and frequency are kept constant, while the position of the pulse within a time slot varies according to the data being transmitted. Commonly used in radio control systems. 3. **Project Portfolio Management (PPM):** A software and management process for centrally managing the aggregate collection of projects, programs, and other related work to effectively achieve strategic business objectives. This involves prioritizing projects, allocating resources, and tracking progress to ensure alignment with overall business goals. PPM software helps organizations select, plan, and execute projects effectively.
