### We are Optimistic - we think we can create software that will help users / make their lives better / make us money (?-yikes!)

### We think we will bash every bug, satisfy every requirement, develop elegant and beautiful code.

### Throwaway Project

> 'You should plan to throw away the first version of anything that you create, be it a user interface design or an engineered interaction. The first version often enables an understanding of the system and aspects of the system development but it should not be confused with a real live deployable user experience.'

--

### Agile Throwaway Project

> 'Agile methods, and to some degree the iterative design cycle, makes accommodation for these constantly changing factors. But you should also realise that even though the project planner or manager may have agreed a specification, that specification is unlikely to be the one delivered.'

### Changes Happen

> 'One thing that has come out of the work of David Parnas, and in some cases may be transferred back, is the ability to think of a software project as a family of related products; Parnas suggests this method anticipates enhanced sideways extensions and versioning.'

--

> 'Applications become highly partitioned enabling user experience people to work on different interfaces for each member of this family of related projects.'

- There is no single development, in either technology or management technique, which by itself promises even a tenfold improvement within a decade in productivity, in reliability, in simplicity; and

- We cannot expect ever to see two-fold gains every two years.

> 'While there might be no silver bullet (indeed the silver bullet may take away some of the challenge, and therefore our fun), the best advice I have is to always keep in mind the pessimistic view of an optimistic visionary 'most people are fools, most authority is malignant, God does not exist, and everything is wrong.'.'
