verdadeira (V) ou falsa (F). As proposições são normalmente
representadas pelas letras maiúsculas A, B, C etc. A partir de
proposições dadas, podem-se construir novas proposições
compostas, mediante o emprego de símbolos lógicos chamados
conectivos: "e", indicado pelo símbolo lógico

proposição; pode-se, também, construir novas proposições
mediante o uso do condicional "se A então B", representado
por A

depende do julgamento que se faz de suas proposições
componentes. Considerando os possíveis julgamentos V ou F das
proposições A e B, tem-se a seguinte tabela-verdade para
algumas proposições compostas.

Considerando-se a proposição A, formada a partir das
proposições B, C etc. mediante o emprego de conectivos (

dos valores lógicos de B, C etc. e diz-se que A é uma contradição
quando A tem valor lógico F, independentemente dos valores
lógicos de B, C etc. Uma proposição A é equivalente a uma
proposição B quando A e B têm as tabelas-verdade iguais, isto é,
A e B têm sempre o mesmo valor lógico.

reviews and inspections. A technical review requires substantial
preparation on the part of the presenters. Documents must be
published and distributed and presentation material organized and
made into slides or overheads. Practice sessions are conducted by
presenters with an audience of critics to prepare for the review.
The reviewers should read the material, attend the
presentations, and write reports. On large projects with many
reviews and walk-throughs involving many participants, a
substantial number of labor hours can be consumed analyzing
documents, attending meetings, and writing reports. For example,
a system design review for one module or unit can require 150
labor hours. When overlooked, this labor can result in a very
large error in resource and schedule estimation.
Many projects include risk assessment and risk
management as a key part of the planning process and expect the
plan to identify specific risk areas. The plan is expected to
quantify both probability of failure and consequences of failure
and to describe what will be done to contain development risk.
