Key Differences

An introduction typically serves as the opening section of a document or presentation, establishing context and outlining the purpose. Whereas, preliminary activities are early actions or experiments that prepare the groundwork for more comprehensive or definitive work.
In academic writing, the introduction provides a thesis statement and a brief overview of the argument, while preliminary research might involve gathering data or literature reviews that inform the scope and direction of the study.
In project management, the introduction in a report presents the project’s goals and significance, on the other hand, preliminary steps might include feasibility studies or initial project scoping.
In legal settings, an introduction can refer to the initial presentation of a case to a court, whereas preliminary hearings determine if there is enough evidence to proceed to trial.
In software development, the documentation introduction gives an overview of the software's purpose and capabilities; preliminary development stages might involve prototyping or drafting initial design specifications.
