Objectives Understand the importance of rigorous documentation Experiment with selecting the right analytical tool for the right job
Inductive VS Deductive Analysis Induction: a method of reasoning from a part to a whole, from particulars to generals, or from the individual to the universal. Example: whenever I let go of a hammer, it falls to the ground. Therefore, every time I let go of a hammer it will fall to the ground. Deduction: a rigorous proof, or derivation, of one statement (the conclusion) from one or more statements (the premises)—i.e., a chain of statements, each of which is either a premise or a consequence of a statement occurring earlier in the proof. Example: All fairies are pink. Tinkerbelle is a fairy. Therefore, Tinkerbelle is pink. Which is better? That’s elementary, Watson. Definitions from Encyclopaedia Britannica 2008
Yes but how? • You should have a range of tools: • Driver analysis – problems, opportunities and standards • Objectives analysis – SMART • Requirements analysis – functional and non-functional • Scope analysis – scope and context • Process analysis – process models and specifications • Data analysis – data models and specifications
The names, not necessarily respectively, of the brakeman, fireman, and engineer of a certain train were Smith, Jones, and Robinson. Three passengers on the train happened to have the same names and, in order to distinguish them from the railway employees, will be referred to hereafter as Mr. Smith, Mr. Jones, and Mr. Robinson. Mr. Robinson lived in Manchester; the brakeman lived halfway between Lancaster and Manchester; Mr. Jones earned exactly $20,000 per year; Smith beat the fireman at darts; the brakeman's next-door neighbour, one of the passengers, earned exactly three times as much as the brakeman; and the passenger who lived in Lancaster had the same name as the brakeman. How can you prove that the engineer must have been called Smith? Deliverables: flipchart presentation that proves the solution is correct…which will be presented by the other team! Time: 60 minutes An exercise in deductive analysis…
Do what you need to do to do the analysis • Use whatever tools you like to document the solution • You could • just write out the solution in narrative • flow chart or process model it • create some custom documentation • Venn diagrams • Something else! • Whatever you do, be rigorous and document everything as the other team will be relying on your documentation alone.
