"Closely timed" can be exchanged with words like "simultaneous," "coordinated," "synchronized," "concurrent," or "sequential," depending on the context. These synonyms refer to events or actions happening at the same time or close to each other in sequence. For example, "The train and the bus arrived simultaneously at the station," or "The dancers' movements were synchronized perfectly to the music." When discussing project management, the term "coordinated" may be more applicable to indicate the careful planning and execution of activities to meet project deadlines. Whoever chooses to use these synonyms should consider the tone, context, and desired level of precision in their use to avoid misunderstanding.
