A reliable system requires redundancies
in every area, including the humans who run the system. Cross-training other people to
perform the tasks that you perform actually makes the system more reliable. In addition, if you
really want to have some evenings at home, rather than babysit a sick system, having a backup is
required. Generally, you want to consider every possible contingency before you start up that automated
system the first time. Expecting it to work without help isn??™t going to be effective; remember
that Murphy fellow who seems obliged to make our lives interesting in the worst possible way.
Think about the Small Stuff
I use checklists for everything. In fact, the book you??™re reading now relied on many checklists to ensure
I didn??™t miss any details (at least not purposely). Checklists aren??™t perfect, but by documenting the process
you use to accomplish a task, you can reduce errors and fix any procedural errors as you continue to
work with the checklist. In many cases, checklists also help you avoid common, silly errors. The type of
error where you wonder what you were thinking about later. Often, these errors occur when you??™re in a
rush, such as at the end of the day when you??™re setting up the after hours processing for the night.
