I think this is a bit disingenuous. There’s no customer interaction in these panels.
So waterfall would be:
Customer says they want to go to Mars.
You spend years building a rocket capable of going to Mars, draining all the company budget in the process.
Customer then clarifies they actually meant they wanted to go to Mars, Pennsylvania, USA - not the planet!
Also the strip stops midway through as Waterfall was an invented thing just for a paper. And during your UP work you actually had the customer put in that input and hence it was like in this cartoon strip.
Waterfall method: talk about building a rocket for 5 years, build the rocket, rocket needs to be totally redesigned because we forgot to put a place for people to go - massive change reqeust, build new version. Project Delay: 27 years
Agile Method: a rocket is not software - do not use Agile
Kanban - kanban is agile
Scrum - scrum . . is also Agile. What are you doing, go back and do the waterfall one
Your comparison is interesting, but let's consider some historical facts. The Apollo program, which successfully put humans on the moon, actually employed many principles we now associate with Agile methodologies.
Contrary to popular belief, it wasn't a straightforward Waterfall process. NASA used frequent feedback (akin to daily Scrums), self-organizing teams, stable interfaces so that teams are an independent path to production, and iterative development cycles - core Agile practices. In fact, Mariana Mazzucato's book Mission Economy provides fascinating insights into how the moon landing project incorporated elements remarkably similar to modern Agile approaches. Furthermore, here's a NASA article detailing how Agile practices are used to send a rover to the moon: https://ntrs.nasa.gov/api/citations/20160006387/downloads/20160006387.pdf?attachment=true
While it's true that building rockets isn't identical to software development, the underlying principles of flexibility, collaboration, and rapid iteration proved crucial to the missions' success. Programs like the Apollo program adapted constantly to new challenges, much like Agile teams do today.
Regarding Kanban and Scrum, you're right that they fall under the Agile umbrella. However, each offers unique tools that can be valuable in different contexts, even outside of software.
Perhaps instead of dismissing Agile outright for hardware projects, we could explore how its principles might be adapted to improve complex engineering endeavors. After all, if it helped us reach the moon and, decades later, send rovers to it, it might have more applications than we initially assume.
Also, Kanban was invented in the 40s as a process for automotive production lines. That's why it aligns so well with maintenance and operations projects in IT. It's ridiculous how more and more people claim it comes from software development and would not fit hardware projects, when that's the core use case of the methodology.
So does Agile even have a definition, or is it just an umbrella for every management method?
Agile methodology is a defined framework for software development success. It helps teams adapt and solve specific needs at a given time and prioritizes accelerated time to market and the value of user insights. Agile is based upon a set of four values and twelve principles laid out in the Manifesto for Agile Software development.
This is waterfall method propaganda! It never works out this smoothly. They probably forgot important requirements like: the astronauts need to be alive on Mars.
Waterfall is missing the part where the customer realizes they didn't actually want to go to Mars they just wanted to view it out of a telescope.
But now they can only travel to Mars and the telescope is out of the budget because you spent so much money on the rocket
2 years later: It's now up to the lawyers to figure out if it's the rocket that doesn't meet agreed requirements or if it's on the customer for not giving proper requirements.
I hate how true this is. Not even 2 years later for my case.
Actual real world right now giant rockets include
-
One that is being built under waterfall methodology. It has been being built for several years. That's the Blue Origin New Glen heavy lift reusable rocket
-
One that is being developed under an agile methodology, it flew as a subscale lander to test their engine and flight control, it has flown four full test flights, improving on each. That's SpaceX's Starship
We are yet to see either launch a payload to orbit
-
Or the funders get bored of waiting after ten years of "no Mars yet" and cancel the project, leaving you with a half finished rocket.
All the projects that have shittier outcomes in my experience is always waterfall. This is mainly because the stakeholders usually have this bright idea to be added in the middle of development that's really need to be added at all costs and then got angry when the timeline got pushed because of their fucking request breaking a lot of shit.
At least scrum has a lead time of around 2 weeks so that when someone has a idea we can tell them we'll add it to the backlog and hope they forgot about it during the next sprint planning.
I'm sure, doth the Astrumants should survive the landing, there should be a way to return, and they need a shitter as part of the missed requirements. As it's a waterfall, that will come in the second, third, and fourth trips.
This is what I came to the comment section for.
If like me you're not a pro, it seems to literally just mean linear phases, so yeah, any nonlinearity would cause problems.
The art style is nice but the content makes no sense. Kanban and scrum are parts of agile. They are not their own systems.
Lean also doesn't mean you have no money. It's a system of manufacturing where you cross train people to do the jobs on either side of them so they can pick up slack if needed and keep things moving without hiring more people.
Lean is also short for putting your inventory in an open top dumpster.
Someone shared this on Mastodon so I'll just repost my thoughts from there. (Bonus for Lemmy, I was forced to squeeze all my thoughts into 500 characters, so this is the most succinct I've been on this site!)
Pretty incredible how little people seem to understand these. For one thing, every method other than waterfall is a subtype of agile methodology. The major distinction is that waterfall has a series of phases from design through building, testing, and delivery that attempts to plan the whole project up front. Agile methods focus on smaller iteration cycles with frequent, partial deliverables.
Something like kanban is designed for continuous delivery: we want to go to mars weekly.
LEAN development is a scam though, that one is accurate.
The author is also hyping up waterfall too much. Agile was created because waterfall has its shortcomings (e.g. the team realizes too late that what they’re building isn’t what the customer wants).
But I also think it also represents how poorly implemented these ideas are. People say they do agile/kanban/scrum, but in reality they do some freak version of these.
The amount of people who say they do agile/kanban/scrum but have never talked to a customer/end user, let alone released something, is frightening
LEAN from the web:
After each iteration, project managers discuss bottlenecks, identify waste and develop a plan to eliminate it.
1st iteration:
Project Manager A: Requiring approval of multiple Project Managers for the same thing is causing a bottleneck. So is having to wait for a specific manager for a specific topic.
Resolution: Let all managers approve everything and need only a single manager's approval.
2nd iteration:
Project Manager B: There are too many redundant managers. It's a waste of resources.
Resolution: Get rid of all mangers but one. Actually, let the engineers manage themselves.
3rd iteration:
Consensus: LEAN development is a scam though
My impression of management science, at this point, is that it's not. The good ones just do it.
Edgy meme: agile bad
NASA: "Yep, we use agile" https://ntrs.nasa.gov/api/citations/20160006387/downloads/20160006387.pdf?attachment=true
Going to the moon as a step towards going to Mars is so eminently correct that this comic should actually be Agile propaganda
It’s like camping in the garden, in the hopes you’ll reduce your commute.
NASA also built the space shuttle, which was a plane that couldn't fly by itself (as it was supposed to), was slower to turn around and more expensive than older equivalent technologies, and blew up all the astronauts 1.5% of the time.
I mean, they're great at other things - who else could have made the JWST work flawlessly with one opportunity - but they're a definite source of hype, and they do something very particular and specialised. Beware endorsements.
Edit: Fuck you, I'm right. Keep 'em coming.
I don't even care about Agile either way. This just isn't a good argument for it.
I can see you're frustrated by the downvotes and pushback you've received. It's understandable to feel defensive when your viewpoint isn't well-received. I appreciate you sharing your perspective, even if it goes against the majority opinion here.
Your points about the space shuttle program's challenges are valid and worth discussing. It's important to note the timeframes involved though. The shuttle was developed in the 1970s, well before agile methodologies emerged in the 1990s and 2000s.
Interestingly, one could argue that NASA may have used agile-like practices in the space shuttle program, even if they weren't labeled as such at the time. However, I did a quick search and couldn't find much concrete evidence to support this idea. It's an intriguing area that might merit further research.
Regarding modern agile approaches, while no method is perfect, many organizations have found them helpful for improving flexibility and delivering value incrementally. NASA's recent use of agile for certain projects shows they're open to evolving their methods.
I'm curious to hear more about your thoughts on software development approaches for complex engineering projects. What do you see as the pros and cons of different methodologies? Your insights could add a lot to this discussion.
What is the methodology called where you:
Plan to go to orbit, blow up seconds into the flight, and declare it a success.
Plan to refuel in orbit, make it minutes before the rocket brakes. Fire the FTS, it fails, the rocket blows up a minute later und declare it a successful test of the FTS.
Argue to NASA that you are not the limiting factor to the moon mission planed for the end of the year, despite delivering none of the milestones.
FTS = flight termination system
That's called R&D, Research and Development. As long as you learn from a failure, it is progress towards success.
Getting to space. Fuck Musk, but SpaceX is doing great work.
An improvement.
This is the Kerbal methodology.
Sounds a bit like the S&M methodology. SpaceX & Musk
Tbh it actually sounds a lot more like Boeing these days. F9/F9H is bulletproof reliable these days, and starship is making HUGE developmental strides, while Boeing is still failing to discover and iron out system integration bugs and hardware faults years after they had “completed the project”.
I call that following the same successful recipe that got us the Falcon 9.
The mindset that considers those tests failures is the same one that would still be in bureaucracy hell determining what 40 year old technology we should repurpose to get a future over budget, late, and under performing solution designed and built.
I take it you missed the recent fourth integrated flight test, in which the ship soft landed on the ocean near Australia as planned and the booster soft landed on the ocean near the launch site as planned
Their failure in that flight was expected. They hoped thermal tiles sealing the hinge for the aerodynamic surfaces would seal those against plasma during reentry. They didn't. Had they, it would have been much cheaper than sealing those more thoroughly. The ship landed regardless of that failure
Disliking Musk is fair, but SpaceX is doing good stuff
It's a feature, not a bug
Cowboy Programming:
PO: Hey we want to go to Mars
- 3 weeks of silence -
Developer: Hey I'm there, where are you?This is the way.
Assuming you know the developer isn't a shitbird, because you're the developer. If this was Investor Humor the idea would be less popular.
PO: Someone else figure out how to repeat what he did.
Second developer: Sorry, I tried to make sense of his rocket design but I can't figure out how to make a copy that doesn't explode before we even put the fuel in.
If the person who drew that comic understood anything about complex systems or why agile works when used properly, it could make sense. But it doesn't.
Firecracker looks proud. Really brightens my night.
The creator does not know Scrum, it's about transparency and not intransparency.
Also Kanban, Scrum and Lean Development are all agile development.
I like how many devs this pissed off. this picture is whack tho wtf
I don't understand the Scrum one. Scrum is also agile with short development cycles, and prioritizes communication with the product owners and stakeholders.
I've never heard of lean development, but not a fan of "lean manufacturing," at least not the way it's commonly implemented in the U.S. (using primarily temp workers so they can ramp up and down their workforce as needed; and it also exacerbates supply-chain problems).
This can be funny but nothing is right. Kanban is not a method and can be found in agile methodology and lean, scrum is also an agile methodology, and they are wrongly defined
Quick google shows that Kanban is a method. Mainlu around picking up things as the come, but also limiting how much can happen at once.
The project I'm has a team that uses Kanban for the "Maintenance" tasks/development, take what is at the top of the board and do it. Adapt if higher priority things comes around, such as prod bugs. Our developments teams are trying to implement Scrum, where interruptions are to be avoided if possible during sprints. You plan a sprint, try to do that work, and can present it, and iterate when users inevitably changes criteria.
In the meme, kanban does somewhat make sense, since getting armrests is never going to get a high priority as part of building a rocket. Scrum isn't exactly right, but I can see where it's coming from. They are all agile methods though.
Kanban is just a board. You can implement different things with it, like pull system, one piece flow, prioritizing, etc...
Like yes, but undone armpits generate more wealth than the rocket to Mars
Heh... Armpits. I know what you meant, but you still gave me a giggle with that one.
Sorry, was writing it from the toilet. Needed to hurry in order to not miss a PBR
Yeah, I remember the time i had a project manager who’d come over from the construction industry, used construction industry metaphors, and thought everything would be the same.
Guess usual (state funded) rocket building is Kanban. Space X and BlueOrigin & co are Agile, except that one that was Lean.
I heard fuckin nasa does TDD
This is depressingly accurate. 😓
