Define Product Design Specification

[arthurrowland]

A living document for the product design specification for the totaliser.

Performance

• Connects reliably to major crowdfunding platforms
• Uses the My Baby's Got LED board to drive LED strips for the effect
• Set-up takes under 60 minutes for a non-techy user, then requires no user input to function
• As quiet as a relaxed laptop
• Capable of turning crowdfunding pledges into dazzling lighting updates and steady totals, understanding how far off the target the running figure is

Environment

• For indoor use: not water resistant
• Temperature Range: -10 to 35 Celsius

Production cost

• Materials: £50
• Labour: £?

Quantity

• 1 off

Manufacturing Facility

• Equipment at DoES Liverpool and 9 Oldham Place: Laser cutter, CNC, SLA and FDM 3D Printers, hand/power tools

Service life

• 2-8 weeks at a time then returned to manufacturer

Size

• Suitable for use on top of a large desk

Weight

• <1kg

Maintenance

• Connectivity can be diagnosed and repaired remotely by manufacturer
• Components can be removed and replaced with common tools

Materials

• Must withstand environmental conditions specified
• Ethical supply, renewable where feasible

Ergonomics

• Any buttons easy to press

Appearance/Aesthetics

• Stylish, curved, aerodynamic design
• Space for (optional) customer's logo

Finish

Customer

• Someone running a large crowdfunding campaign

Documentation

• Open Source and documented on MCQN's Github

I tweaked the aesthetics section to make it clearer that the logo isn't ours (although somewhere we'll need the MCQN logo and its ibal number, but that won't be front-and-centre :-)

Another possible use case would be a software team (or anyone else working on projects) to show progress towards a sprint or a milestone, with a "progress event" indicator when an issue gets closed.

Added some accessibility specifications. If the totaliser gets promoted from prototype to product, we may want to include some audio to match the visuals, and look closely at the customer experience of renting the product (accessible website, instructions and communications).
