There is information useful to any developer. Some quotes:
" Misconception 3: Planning in software engineering is worse than in other areas ')
[...] Flyvberg, Bruselius and Rosengatter give examples of several well-known projects with large budget overruns:
Suez Canal (1869) - 1900% overrun; Sydney Opera House (1973) - 1400% overrun; Concorde (first flight in 1969) —1100% overrun; Panama Canal (1913) - 200% overrun; Brooklyn Bridge (1883) - 100% overrun. "
" Misconception 4: The user interface is developed during low-level design
“Now we are not up to problems with the user interface.First we have to make this thing work! ”, Say Mulligan et al. [20].However, the importance of the user interface is hard to overestimate: in the dialogue system, about half of the code is related to it.A recent study showed that 60% of software defects are impractical and only 15% are related to functionality [21].Due attention to the quality of the user interface on e-commerce sites can increase sales by 100% [22].
