Considerations around affordances and sustainability

Category	Questions to ask
Affordances	Is the technology synchronous or asynchronous? Can it be accessed and used by few or many people? Can it be loaded onto a mobile device or do you need a big screen? Will the users need to download programs or is it a web application?
Sustainability	How easy is it to update the learning material? How widely used is this technology and who supports it? (In general, solutions supported by a user community or a large company are less likely to disappear than those created by small entrepreneurs.) Can content be exported into another technology if your current solution is no longer supported?
