On of the most insidious phrases to sneak into agile is "at the end of the sprint".

Stop obsessing about the sprint boundary and worry about continuously delivering value and getting feedback instead.

Hotter take: 99% of these statements mean Scrum when they say Agile.

Scrum is training wheels for agile and is not agile. Yes, it will get you around the track but you *need to figure out how to ride*.

"just being organized" is very rare and incredibly effective when found. https://twitter.com/PaulDJohnston/status/1537733160850579456

And yet in the comments you mention a kanban board (an agile technique) as something that works.
 Sat Jun 18 02:11:57 +0000 2022

Replying to @PaulDJohnston

It sure does. But using it within software development (not automobile) in an agile manner does not.

Unless you're proposing that the only thing that exists in all of agile is scrum itself? (Which simply does not exist in the Manifesto)

 Sat Jun 18 15:36:05 +0000 2022

Replying to @PaulDJohnston

Because you're said you're not talking about scrum. How do you see non-scrum implementations of agile to have failed?

Replying to @PaulDJohnston

I'm sorry you're frustrated. From the field, I've seen a lot more bad implementations of agile help people at least get organized, than I have the same from merely urging people to do the same. Only one effort is changing the system.
Otherwise, it's just Deming's red beads.

Must be. All I'm reading now is: someone that does something well in a system that makes them happy often gets more benefits than they would in a badly implemented system.
 Sun Jun 19 21:28:15 +0000 2022

Replying to @davemangot

The delay in adding the new hire to the rotation because they have to learn the oddball system.

The cognitive load of being on call for something that is barely tested or maintained

The activity to patch and deploy something that is hard to build and scarcely tested.

 Tue Jun 21 17:18:56 +0000 2022

With recent bear market dips, it’s a good time to shut down marginal products rather than maintain those which generate little revenue/are not the future of the company.

Often finance sees revenue, and some bills, this is what they don’t see. 🧵

 Tue Jun 21 17:18:56 +0000 2022

Replying to @davemangot

The time it takes to run security scans and tests just so they are documented, not because they will be fixed.

The additional burden on the one SRE who still understands something about the marginal system because they’ve been around the longest.

 Tue Jun 21 17:18:57 +0000 2022

Replying to @davemangot

The periodic fires that need to be put out when a customer does something unexpected or we’re the subject of a Denial of Service attack.

The cognitive load on the security folks for a product with known XSS, CSRF, etc. vulnerabilities that they know no one will patch.

 Tue Jun 21 17:18:57 +0000 2022

Replying to @davemangot

The load on the project manager who still has to report on the status of the marginal product because if she does not, people might forget that it exists.

The additional attack surface the company is vulnerable to for a product that barely makes a profit.

 Tue Jun 21 17:18:58 +0000 2022

Replying to @davemangot

The cost to bring in a developer contractor to perform one-off fixes on the legacy product because it’s been “unstable lately”.

 Tue Jun 21 17:18:58 +0000 2022

Replying to @davemangot

The multiple contracts that must be maintained for legacy software tools (licenses, etc.) that are needed to support the legacy product.

 Tue Jun 21 17:18:59 +0000 2022

Replying to @davemangot

The toil (deleting files, growing partitions, adding resources, etc.) that must be performed to keep the site up and running as no software runs forever without intervention.

 Tue Jun 21 17:18:59 +0000 2022

Replying to @davemangot

The time customer success spends on calls for the marginal product instead of developing stronger relationships with high value customers.

The context switching staff must do when paged about the oddball product which takes them away from high value work.

 Tue Jun 21 17:18:59 +0000 2022

Replying to @davemangot

The different meaning of this term or that term in the marginal product because it was either brought in via acquisition or named before the rest of the company had standardized.

 Tue Jun 21 17:19:00 +0000 2022

Replying to @davemangot

The exceptions that must be carved out in new platforms and processes to account for a system that will not be modified because of the difficulty in doing so.

 Tue Jun 21 17:19:00 +0000 2022

Replying to @davemangot

The efforts, contracts, and manual work it takes to maintain this one product in a data center when everything else has moved to the cloud because “our monthly data center bill is cheap!” If it stays within its power and cooling allotment, of course.

 Tue Jun 21 17:19:01 +0000 2022

Replying to @davemangot

The additional difficulty it takes to troubleshoot problems with the product because it doesn’t use modern or standard company tooling and everyone who’d developed it has left.

 Tue Jun 21 17:19:01 +0000 2022

Replying to @davemangot

The promise Engineering gave to the company that they would sunset the product in 3 years, but 3 years later, they are finally beginning to make progress, and it will only take 3 years (from now).

What have I left out? LMK in the replies.

 Tue Jun 21 17:19:02 +0000 2022
