Project types refer to the various categories of projects based on their characteristics and objectives. Common types include construction projects, which involve building structures; research projects, focused on exploring new ideas or technologies; and IT projects, centered around software development or system implementation. Each type has its own unique processes and requirements. Additionally, projects can be classified by their scope and duration. For instance, short-term projects are completed within a few weeks or months, while long-term projects may span several years. Understanding these distinctions helps in effective planning and resource allocation for successful project execution.
