"Outcomes are the results the client gets from your work"

"clients only really care about their own business. [Moi ici: Como escrevo há muitos anos, os clientes são egoístas] By this, I mean:
.
They don’t really care about how much it costs you to complete the work
They don’t care what you have to do, or how much time & effort it requires on your end
They don’t even care about how well-crafted the work is for its own sake
That’s not to say they don’t care about quality or deadlines (these things obviously matter), but what really matters are the OUTCOMES and the IMPACT of your work.
.
Let’s take a second to define precisely what these terms mean.
.
When we sell to clients, we sell four things:
.
Inputs are the resources used to deliver a project – people, time, software etc.
Outputs are the completed tasks & deliverables e.g. a logo design, a press release, or a new website
Outcomes are the results the client gets from your work, typically characterised as a transformation e.g. unaware prospects start to notice their business or their branding goes from non-existent to some awareness
Impact is the long-term benefit of the work you’ve done – e.g. securing a leading position in their niche, getting many new enquiries, increased sales & profits etc.
Inputs and outputs are easier to quantify, but they matter a lot less than outcomes and impact.
.
Focusing on the former two is a hallmark of agencies focusing on the wrong thing and therefore likely to lead to misunderstandings and shorter-term relationships.  Rather than framing their work in terms of how it will benefit the client, they instead spend their time worrying about the stuff that’s easily measured. Sadly, this is one of those cases where choosing the simpler upfront option holds you back in the long run."
