• This system should be accessible

• The device should be useful

• The system should be Marketable

• The system should be valuable

• Monitored status should be accessible remotely, private, user friendly

Intended Users and UsesIntended Users and Uses

• UsersUsers

– Computer LiterateComputer Literate

• UsesUses

– monitor the status of gas and smoke monitor the status of gas and smoke concentrations, and intrusionconcentrations, and intrusion

Feasibility AnalysisFeasibility Analysis

Concept DevelopmentThe pros and cons of selections• Advantages:

– Power – Wireless– Serial– Individual connections

• Disadvantages: – Wired systems may be more costly – Cumbersome– Constant battery replacement– Signal interferance– Serial Signal Delays

Standards

• ISO 7240-1– connected to control and indicating equipment

• AS/NZS 4379.2:1996 – the remote database access client, when

database language used is SQL

• ITS-90– t90 / °C = T90/K - 273.15

Ethical ConsiderationsEthical Considerations • DilemmaDilemma

– unauthorized access to private information – security risk from altered information

• StakeholdersStakeholders– The stakeholders involved in this project will be the owner or

other users of the security system, hackers, and the general public.

• Determining the optionsDetermining the options – Best extreme – Worst extreme – Compromise

• Application of Ethical TheoriesApplication of Ethical Theories – Ethical egoism – Utilitarianism – Ethics of care
