A visual presentation technique used to overwhelm the audience. A standard strohgraph is a directed-graph structure with individual elements and edges that employ absract shapes, vibrant colours, the most current Just-in-Time buzzwords, and Three Letter Acronyms (TLAs). Clinical studies have shown that prolonged audience exposure to strohgraphs can produce many negative side-effects such as: loss of funding, mandatory .NET use, hemorraging of the sensory organs, renal failure, and death.
No, you don't have to erase that. See if you can fit into the strohgraph and then write up a requirements document to fit the new system.
