Digital sufficiency consists of four dimensions

(a) hardware sufficiency, which aims for fewer devices needing to be produced

(b) software sufficiency, which covers ensuring that data traffic and hardware utilization during application are kept as low as possible

(c) user sufficiency, which strives for users applying digital devices frugally

(d) economic sufficiency which means living within planetary boundaries.
