251 ;;Quote: even though there is not a rational way to design software, we can fake one; i.e., present a system as if it were designed rationally
356 ;;Quote: software development is not rational; do not know what is wanted; can not tell what is known
251 ;;Quote: human errors are intrinsic to being human
252 ;;Quote: rational design requires a requirements document
253 ;;Quote: a requirements document should contain everything needed to write acceptable software and no more
359 ;;Quote: organize a requirements document as a reference document instead of an introductory narrative; worth the expense; easy lookup
253 ;;Quote: a requirements document is primarily a set of tabular, mathematical functions from external state variables to single output values
360 ;;Quote: a requirements document includes the host specification, interface specifications, a specification for each output value, timing and accuracy constraints, likely changes, and undesired event handling
253 ;;Quote: a module guide states the design decisions that will be encapsulated by each module
253+;;Quote: a module guide defines how work will be divided into work assignments
254 ;;Quote: a module interface specification is a formal description of each module as a black box; allows independent development
254 ;;Quote: a module design document records the major design decisions for design reviews and documentation
363 ;;Quote: use pseudocode in design documentation; keep both versions consistent; use different programmers
364 ;;Quote: keep design documents consistent with a system; if multiple versions are required, confine the differences to small modules
364 ;;Quote: in documentation, avoid stream of consciousness (write as think) and stream of execution (write as it happened); difficult to find information
365 ;;Quote: design a document by stating the questions, one per section; then write the document by answering the questions
365+;;Quote: define one and only one place for every fact
256 ;;Quote: include all design alternatives in the documentation along with why they were considered and why they were rejected
