Gane Sarson Diagram
What is the Gane and Sarson Model?
"The Gane & Sarson method is based on the building of a logical model of the system, using graphical techniques to enable users, analysts, and designers to get a clear and common picture of the system and how its parts fit together to meet the user's needs.
The methodology involves building a system top-down by successive refinement. First, an overall system data flow is created. Then, detailed data flows are created. Next, the details of the data structures and the process logic is determined. Finally, design of modular structures is begun.
The focus of analysis in the Gane and Sarson method is the Data Flow diagram, which is used to describe the processes of the system, and how the processes transform data."

The first step to improve your workflow is to draw it down. When the workflow is visualised you are able to analyse it, to find excess or missing steps or relations. Changing the workflow on paper you can pass as many iterations as needed to get the optimal process, and then start implementing changes to the real process. The best software helps you with workflow is ConceptDraw DIAGRAM software extended with the Workflow Diagram solution. It contains all tools, features, samples and templates you may need during drawing workflow, analysis, and then presenting and implementing your results.

If you have no time, you can create a SWOT diagram even on asphalt using a chalk. Although, in case you want a proper scheme, you should use a special software for creating SWOT analysis diagrams that would be comprehensible. SWOT analysis is useful not only for business purposes, but even for cities or for a particular person.
The ConceptDraw SWOT and TOWS Matrix Diagrams solution is a tool for performing both SWOT and TOWS analysis. It provides templates of different sorts of Matrix Diagrams. Besides different embedded templates, the solution enabling create custom SWOT and TOWS matrices. Using the compatibility between the MINDMAP and DIAGRAM is the best way of making SWOT or TOWS diagrams quickly. The mind map templates help identify the core statements of SWOT and TOWS analysis: Strengths, Weaknesses, Opportunities, and Threats. The next step is matrix creation - both SWOT and TOWS analysis use the same basic steps and the only difference is the order in which these criteria are studied.

A workflow diagram is less general notation than a process flow diagram. Workflow as a term can apply to organizational process which involves people, resources, documents, sort of data, for instance; whereas a process is general collection of steps occuring in any sort of activity. That is why process flow diagram can be used as workflow diagram to describe business process, data flow or department interactions.
The fastest way to create a workflow diagram is using pre-designed workflow template. ConceptDraw DIAGRAM with the Workflow Diagrams solution delivers rich set of workflow diagram templates you may start from.
