Sammanfattning	A pilot-tested experiment log is a structured research instrument — a systematic journal of experimental procedures, observations, and results — that has been trialed with a small representative sample before full deployment. The pilot phase identifies ambiguous recording fields, impractical time demands, or inconsistent terminology, enabling targeted revisions that improve the log's reliability and completeness before the main data-collection phase begins.	Document collection is a systematic data-collection technique in which the researcher gathers and reviews existing written, visual, or digital records — such as reports, meeting minutes, policies, letters, photographs, or institutional records — as primary or supplementary evidence. It is widely used in qualitative, historical, and mixed-methods research and can stand alone or complement interviews and observation.
