Stakeholders

• People living in the House• Impaired ability users• Pets• Supermarket• Emergency services (fire, police, nursing)• Property developers (corporate and individuals)• Competitors• Software Developers• Hardware Specialists• Installation and maintenance engineers

High level goals and assumptions

• We are a company developing the system for market, we need software to operate with available generic hardware to make a new a product

• The most desirable feature should be the automated shopping

• Busy (or lazy) people want to use the system to save time• The system can be used by the elderly and infirm to

support independent living• System must be reliable because it can preserve life• The system should be modular so that people can buy

the pieces that suit their needs

High Level goals (2)

Work to be done• Automated shopping

– Suggests a shopping list to you and allows you to place the order automatically.

• ‘Reminders’ system• ‘Follow-me’ lights and music• Emergency responses

– Fire, the fire service– Break-in, security company or police– Fall and injury triggered by assistance alarms, nursing response

Obstacles

• The most desirable feature should be the automated shopping

– Agreement of supermarkets

– Compatibility with their systems

• Busy (or lazy) people want to use the system to save time

– time needed to operate the system

• The system can be used by the elderly and infirm to support independent living

– complex operation

• System must be reliable because it can preserve life– Power failure

Timescale and Cost

• We classify the project as ‘horse’ type– Some of the work is life-preserving, will impact cost

• Some complexity - there are several types of ‘work’• Relatively few stakeholders, mostly internal

– Our staff – engineers, sales team– Our customers – the householders/property developers
