I have used following simple tweaks to produce great benefits in our endeavor of shipping value to the market.
To implement these tweaks we spent zero money and it does not ask for any certification either. All it took was an open mind and some practice.
Maybe this could help your teams too.
1) Parallel Testing:: It needs some mindset change. All it requires is Dev+QA participation while PM/PO describes the User Story and a common desire by Dev+QA to produce good code.
An additional benefit of this practice would be, QA folks will stop thinking that "Logging MORE bugs" is the yardstick of their performance.
QA folks would start writing the potential pitfalls (aka TestCases) even before Developers start coding, and WHILE they are coding. This would immensely help the Developers to produce good code. QA folks would inculcate a thinking that NOT allowing a bug to creep in, is the real yardstick of their performance.
Just merge these 2 columns into a single column and call it “Building”. You will see the magic it makes for collaboration, particularly between Coding and Testing functions.
A work-item (UserStory / UserStorySlice) in this column becomes joint ownership of Developers & Testers. Any work-item will come out of this column, only when Developers AND Testers feel happy about it.
You will see how radically it reduces to and fro between Dev & QA.
3) Vertical Slicing:: Slicing User Story needs zero money. However it needs some practice by PM/PO. It also needs some change in the way PO & Dev decide to ship. It needs some curtailing of ambition for Shipping the entire User Story in one go.
This sounds a bit counterintuitive, but this is extremely effective as it avoids a good amount of wastage from being built.
4) Information Radiator:: Radiating only those metrics that matter is crucial. Deciding your North Star metrics involves some thinking, actually a good amount of team thinking, (sometimes involves heated arguments within the team). A team needs just 2 things for an Information Radiator
(a) a brutally transparent way of working and (b) a large monitor placed in a common area.
Placing your Information Radiator in the corridor on the way to the coffee machine (like something shown below) is a perfect choice. Radiating the information to ALL (within the team as well as outside the team) is the key. The money spent on the large monitor will be paid back 100 times in a matter of 2 months.
Information Radiator nudges us to focus on the right questions and helps us to avoid wasting time on bike-shedding.
5) Acceptance Criteria:: Start working on a UserStory only if it mentions some Acceptance Criteria (even if it is minimal). Inculcating this discipline of mentioning Acceptance Criteria costs zero money and this practice will reduce the chances of getting a boomerang from the customers. It nudges the PO to develop good outward focus and that hugely helps the PO while describing the User Story to the team.
At the same time, the team (particularly the Dev Team) must keep in mind, that insisting on Acceptance Criteria is just to nudge ourselves for a better discovery process. It should not be treated as a Contract.
