tailieunhanh - Writing Better Requirements

Why do requirements matter? Experience has shown that insufficient attention is paid to requirements. The price paid for this lack of focus and applied practices is systems that don't meet customer needs; take longer to develop than planned; and cost more than customers are willing to pay. Are we ready to change? Are you willing to spend some time and effort involved in practical exercises to experience how better requirements should evolve? If yes, commit to digesting the counsel of two experienced practitioners and to changing current practices to ones that will produce better results | PEARSON EDUCATION LIMITED Head Office Edinburgh Gate Harlow CM20 2JE Tel 44 0 1279 623623 Fax 44 0 1279 431059 London Office 128 Long Acre London WC2E9AN Tel 44 0 20 7447 2000 Fax 44 0 20 7447 2170 cseng First published in Great Britain in 2002 Pearson Education Ltd 2002 The right of Ian F.
