Team's successes and measurements

You could consider Evidence Based Management:

Maybe teams aren't delivering value objectively, and that's what you need to evidence. It doesn't sound as though value is understood here, or that anyone can really account for it right now.

So never mind about trying to "showcase" anything to "program management". There are organizational impediments to agile practice for which servant leadership is required. That's what needs exposing and those senior leaders may need to be put to work.

Yeah I tend to agree with Ian. 



You're asking about measuring value, but then referencing things designed to measure outputs. 



I'd go as far as to say that measuring output is actually a BAD idea until you can define and understand value in your context. 



There isn't going to be a one size fits all, but customer satisfaction, product use, sales, and all sorts of other indicators can tell you if what you're producing is valuable. 



But the best guide is just to spend as much time listening to as many customers as possible. 



Once you have that, you can measure things like cycle time, velocity etc. 



The most interesting and common result though, that will probably surprise you, is that these two concepts tend to  be inversely related. 



Ie, customer value and satisfaction goes up as we deliver LESS. 



getting to that point of visibility is usually the point that conversations get really interesting. 

You know, at the end of every Sprint you have an item to add to the list of thigs delivered: the Sprint Goal.



If that's what you report, the team will be incentivized to focus on the Sprint Goal.



If your management wants numbers, ask them why, and explain software developers are highly schooled creatives. How do you measure a musician's work? Notes played? Songs performed? Are we sure they don't play out of tune if we measure how many notes/songs they played? No, you have them deliver value, and measure the happiness of the public.

I'm going to jump on the bandwagon.  I do not believe that there is any kind of a number you can use to measure value delivery.  That is because value to one person is not the same "number" as it is to someone else.  That is why if you go to a store to buy a shovel, it is the same price to everyone.  But a person that uses that shovel once a month will see a completely different value statement than the individual that uses everyday. 

Everything that my counterparts have said is true.  Stop thinking in terms of metrics with numbers associated to them and find ways to show the value that is being derived from the stakeholders.  And remember that a stakeholder does not have to be someone outside your company that uses a product.  Your internal marketing department, your support department, your IT department, local or federal government could all be stakeholders depending on the work that is being done.
