Reread an older post by Bob Marshall on What is Value?.
While there can be many debates on the topic, the last section is a gem!
I quote it here:
If we undertake to deliver some feature or story which does not directly address this active constraint, then we are failing to deliver anything of (immediate) value. If it’s not of immediate value, then it has no utility, and in fact it’s a negative effort – in that it is simply adding to Inventory (assuming it has some redeemable value in the future) or becomes a write-off as an Operating Expense (assuming it turns out to have no redeemable value).
Thus, the most valuable thing to deliver to a customer is only, ever, something that addresses their current constraint. Actually, not only the most valuable thing to deliver, but the only valuable thing we can deliver.
It may not be immediately obvious, but a moment’s thought along this line of reasoning will also show that many constraints in an organisation will never be addressed or addressable by software. In which case it’s better to suspend work on – and delivery of – all stories until such time as the current constraint shifts and the software does address the (new) current constraint.
Of course for this to work, you need to know what your customer’s constraint really is - and that requires second or third order thinking!
