I would start by drawing it out as a job sequence. As soon as batch processes move from the simple serial, and have dependencies, I get down a visual representation I can use in development and to provide both to scheduling and support colleagues.
Then I would open the manual for LSF and look at its requirements for job definitions and translate the drawing into each step. Then I would offer a colleague a cup of tea to sit beside me while I show them the drawing and explain how the batch is expected to work. If I don't pick up errors as I explain, and my colleague finishes their tea in silence, then I'd pass the instructions over to scheduling.
