Process Analysis & Documentation- A process is a group of resources and activities which processes inputs into outputs by value addition by executing repeatable tasks in a specific order.
Process Modeling
Flow charts, process maps, written procedures, and work instructions are tools used for process modeling and documentation.
Flow Charts – A flow chart or process map is a simple graphical tool for documenting the process flow which is comprehensible to users as it depicts the process sequence. Common flow chart symbols are
Process Mapping – It depicts a process in schematic format thus providing the ability to visualize the process under review. Process mapping is similar to flow charting, as it describes a process with symbols, arrows and words thus avoiding explanations.
- Written Procedures – Written procedures helps in standardizing the processes thus also enabling improvement avenues for the process.
- Work Instructions – Written instructions are list or sequence of steps to be undertaken usually by the operational staff for accomplishing a specific task.
Process Inputs and Outputs
Before a process can be improved, it must first be measured. This is accomplished by identifying process input variables and process output variables, and documenting their relationships through cause and effect diagrams, SIPOC and other similar tools. Inputs (Xs) are causes which are independent variables which results in specific outputs (Ys)
- Cause and Effect (Fishbone) Diagram – They are also called as Ishikawa diagrams and have been discussed earlier. A fishbone diagram development consists of brainstorming, prioritizing and development of an action plan.
- SIPOC – SIPOC stands for Suppliers-Inputs-Process-Outputs-Customers and has been discussed earlier. SIPOC addresses issues regarding the input, output, supplier and customers
- Relational Matrices – It is a relational matrix that is used to assess the effect of each input (X) against its output (Y) in a process.
