A programmable workflow environment grants more flexibility to conduct an observation. This paper provides an easy
way to develop visual workflow control. Users can drag and drop command elements to make up a workflow. The
workflow supports sequence and parallel patterns. When a workflow starts to run automatically, a full set of manual
interventions is supplied, which enable users to cope with unpredictable online situation. Beside this, rule check is
implemented to workflows, which ensures there is no incorrect operation sequence in a user-defined workflow. Rules are
not permanent. They can be modified or added if necessary.
