I'm in a new contract where they seem to have gone overboard with Agile, including hiring a consultant merely for facilitating Agile processes. Something he is instituting is a notion of "core hours" where we will all actually be in the same room together. Is this really what "core hours" constitutes? I ask because it's highly inconvenient to pick up my laptop and go to this shared location for half the day; I always thought "core hours" meant you were available, not necessarily in the same room, from 9:30 to 4, for instance.
Yes and no.
Core hours are the period(s) when all team members commit to working on the project (and not doing administrative stuff or other projects). For many teams, this will imply being in the same room, but with proper planning and the necessary infrastructure, the team can work well from different locations.
I think what you have is an extension of the "core hours" where you are. The idea of being in the shared location is that ad-hoc meetings could occur as well as possibly being within earshot of various discussions so that you can jump in if it is something where you think your opinion or knowledge would be useful, e.g. why was this coded like that? or why do we have this requirement? kind of thing.
I'd like to think that I'm up to date on the Agile world. In reality I am not. With that being said, I'm not so sure this is an agile concept but rather a convenient way for the team to collaborate. It sounds more like something out of Peopleware.
As goes with any team and trying something new, one, there will be resistance to change and two, the team should really have buy in to the new process and working methodology. The Agile consultant shouldn't just be barking orders of what you need to do. He should also be explaining and convincing you why this is a good thing. If you already think the company has gone "overboard" then I think something is wrong. Agile is a great way to work for a many (but not all) teams and shouldn't evoke a reaction like that
Having core hours makes sense so that there is an overlap for collaboration. Having people work in a more open space, maybe 4 people per large cube instead of 1 per small cube, also helps foster collaboration. At work I can just spin my chair around and there are 2 people right there who can help me out or answer questions. However, trying to force something that is uncomfortable and inconvenient defeats the purpose.
I think it would be better to tear down the cubicle walls and rearrange the cubes to make the evirnonment more collaborative.
Slightly off topic but won't fit in a comment:
Agile is extremely disruptive of a programmers "Normal Practices". The word Agile means you are going to have to adapt to changes, I recommend you try to accept them and not fight, because one of adaptations is to cut out team members that cause disruptions in the team.
A consultant is virtually required for a smooth, quick transition.
If your consultant is doing it right, you should be much more unhappy than you seem. During those core hours, none of you should have your own computer--you should be sharing a group. If things are done right, you should be coding in a "Bullpen" without cube walls (facilitates pairing and general communication).
But there are various levels to Agile, and it's intended to be adaptable. Many programmers have a problem with pairing, so often it isn't forced, or is just recommended.
At any rate, it sounds like your consultant is taking it pretty easy on you guys. Try to drink the cool-aid and relax, it'll all be over soon.

I am a long time agile advocated but one of the things that bothers me about Agile is that a lot of agile practitioners, especially the younger ones, have thrown out or are missing a whole lot of good (non Scrum, non XP) practices. Alistair Cockburn's style of writing Use Cases springs to mind; orthogonal arrays (pairwise testing) is another.
I read mostly Agile related books and articles and work with mostly Agile folk ... is there anything I'm missing?
It might be interesting in 5-10 years time to see how maintainable these systems are when nobody wrote down why a particular decision was made and all the people involved have left.
is there anything I'm missing?
Yes, I think a lot, but only if you are interested in Softawre Development Processes.
I like this paraphrase:
Each project should be as agile as possible but not more agile.
Not every project can be agile... but I think 80%+ can.
I see Agile as "car of the year". It is very well suited for most of the people, but if you need/want something special, for example car able to speed 300KM/H or car able to carry 20 tons of goods you need something else.
There is also so many cases when one may want something else than "car of the year" that requires a book to write them down :-) I recommend you Agility and Discipline Made Easy: Practices from OpenUP and RUP. In this book you'll find many "missing parts" very well illustrated. The key to understanding is that Agility is only a (requested) property of software development process which sometimes cannot be achieved. The book describes several Key Development Principles (which are basis for RUP) and explains which level of "ceremony" and "iterativeness" follows from using them on different levels of adoption.
An example
Practice: Automate change management and change propagation
In your project you may require very advanced and strict change management and decide to "Automate change management and change propagation" by implementing custom or re-configuring existing tools and by using Change and Control Board.
Effect: This most probably increase level of "ceremony" in your project.
(...) have thrown out or are missing a whole lot of good (non Scrum, non XP) practices.
Scrum is not prescriptive, it's up to you to choose how to do things. In other words, nothing forces you to use User Stories for example (even if User Stories work for lots of teams, there is no consensus) so feel free to use (light) use-cases if you think they are more appropriate in your context. To illustrate this, Jeff Sutherland reported he would never use User Stories again for PDA device projects (they use some kind of "light specifications" in his current company). And the same applies for testing, use whatever works for you. To summarize, if you find XP not flexible enough, use something else... and inspect and adapt.
Iterative development.
In practice, agile teams may do iterations (or anything for that matter, agile is a kind of "true scotsman"), but agile processes don't require or define iterative development sufficiently.
Take RUP, for example - clumsy and bloated, it does compile a few good methods for long-term development that agile misses.
On a general note, agile is a way to steer clear of problems: how to avoid long term planning, how to keep teams small, tasks short, customers involved, etc. It works more often than not, but sometimes you have to face and solve problems: how to reach strict deadline, make big team work, achieve distant and complex goals, make customer refine requirements. That's when one needs to look beyond agile.

When you have sprint task in Scrum, where do you put how you want to program something? For example, say I am making a tetris game and I want to build the part of the game that tracks the current score and a high score table. I have my feature, my user story and my task, but now I want to talk about how to design it.
Is that design something that is recorded on the sprint somewhere as to how to do that or is that just somethign the programmer figures out. Do you put do task x use database such and such, create these columns, etc.? If not, do you record that at all? Is that what trac is for? I don't mean too high level design.
I touched on it here: Where in the scrum process is programming architecture discussed?
but my current question is later in the project after the infrastructure. I'm speaking more about the middle now. The actual typing in the code. Some said they decide along the way, some team-leads. Is this is even documented anywhere except in the code itself with docs and comments?
edit: does your boss just say, okay, you do this part, I don't care how?
Thank you.
There can be architectural requirements in addition to user-specified requirements that can muddy this a bit. Thus, one could have a, "You will use MVP on this," that does limit the design a bit.
In my current project, aside from requirements from outside the team, the programmer just figures it out is our standard operating procedure. This can mean crazy things can be done and re-worked later on as not everyone will code something so that the rest of the team can easily use it and change it.
Code, comments and docs cover 99% of where coding details would be found. What's left, if one assumes that wikis are part of docs?
Scrum says absolutely nothing about programming tasks. Up to you to work that out...
Scrum doesn't necessarily have anything explicitly to do with programming - you can use it to organise magazine publication, church administration, museum exhibitions... it's a management technique not explicitly a way of managing software development.
If you do extreme programming inside scrum, you just break your user stories for the iteration down into task cards, pair up and do them.
When I submit tasks to my programming team, the description usually takes the shape of a demo, a description on how the feature is shown in order to be reviewed.
How the task will be implemented is decided when we evaluate the task. The team members split the task in smaller items. If a design is necessary, the team will have to discuss it before being able to split it. If the design is too complex to be done inside this meeting, we will simply create a design task, agile/scrum doesn't force how this should be done (in a wiki, in a doc, in your mind, on a napkin, your choice) aside for saying as little documentation as possible. In most case the design is decided on a spot, after a bit of debate, and the resulting smaller tasks are the description of how things will be done.
Also, sometimes the person doing it will make discoveries along the way that change the design and so, the way to work on it. We may then thrash some cards, make new ones. The key is to be flexible.
You do what you need to do. Avoid designing everything up front, but if there are things you already know will not change, then just capture them. However, corollary to YAGNI is that you don't try to capture too much too soon as the understanding of what is needed will likely change before someone gets to do it.
I think your question sounds more like you should be asking who, not when or where. The reason Agile projects succeed is that they understand that people are part of the process. Agile projects that fail seem to tend to favor doing things according to someone's idea of "the book" and not understanding the people and project they have. If you have one senior team lead and a bunch of junior developers, then maybe the senior should spend more of their time on such details (emphasis on maybe). If you have a bunch of seniors, then leaving these to the individual may be a better idea. I assume you don't have any cross-team considerations. If you do, then hashing out some of the details like DB schema might need to come early if multiple teams depend on it.
If you (as team member) feels the need to talk about design, to so some design brainstorming with other team members, then just do it. About the how, many teams will just use a whiteboard and brain juice for this and keep things lightweight which is a good practice IMHO.
Personally, I don't see much value in writing down every decision and detail in a formalized document, at least not in early project phases. Written documents are very hard to maintain and get deprecated pretty fast. So I tend to prefer face to face communication. Actually, written documents should only be created if they're really going to be used, and in a very short term. This can sound obvious but I've seen several projects very proud of their (obsolete) documentation but without any line of code. That's just ridiculous. In other words, write extensive documentation as late as possible, and only if someone value it (e.g. the product owner).

We have proposed to use Scrum in our IT Project and our Adviser asks us if it is appropriate to us because we are still amateurs.
Is it appropriate to us Scrum even if we are amateurs?
The discussion is usually agile vs. waterfall, right? I am linking an article, but it is in Portuguese, so I'll try to transmit some of its ideas:
Waterfall is like chess. You think and plan a lot, try to foresee every possible issue as soon as possible. There's a lot of planning, but makes sense only on stable and well-known domains, where change isn't much expected.
Agile is like soccer (or many collective sports): decisions are made in-game and should be done fast. There's no much time to analyze every consequence. It is "ideal" for dynamic and unstable domains, where change is always expected (web applications, for instance, tend to fall in this category). Another point to note is: even if you have the best players, if they don't do well as a team, you won't be the winner.
IMHO, Scrum would be useful, because:
Once every two weeks (or every month, depending on iteration time) you'll be able to see what's working or not. And this is very valuable, specially as an "amateur" team, which is expected to be learning and finding things out much more constantly.
As amateurs, you probably won't be able to foresee everything (and that's something agile embraces)
There's more space for sharing experience (stand-up meeting, retrospective, and even planning meeting). And you share REAL experience (you must write code every week rather than just plan)
Here's the rub. I think Scrum is going to be tricky not because your team is a bunch of amateur developers but because your team is a bunch of Scrum amateurs. If you have an experienced Scrum Master, your team may reap the benefits of Scrum. Without a point person with Scrum experience, however, there's going to be overhead in learning as you go and more than likely you will get off the Scrum path quickly. At best, you will exercise a modified-Scrum approach (which isn't necessarily a bad thing.) I don't mean to sound negative or doubt your team's ability to practice Scrum, it's just best to have someone with prior Scrum experience before your team dives in. Best of luck.
Scrum, along with other agile methodologies, is not appropriate for a team that consists of students or otherwise inexperienced people.
Wikipedia has a good section on the suitability of agile software development. Barry Bohem and Richard Turner, leading software engineers, wrote a book that includes factors that can help determine if a plan-driven or agile methodology is better on a given project. One of the cases where plan-driven methodologies stands out is with junior developers, which includes students and amateurs.
Now, this doesn't mean that you need to use only a plan-driven approach. I personally think that the most important thing you can do is to find a process that works for your team. You can probably incorporate agile approaches - test driven development, continuous integration, pair programming - into a plan-driven environment that visits each lifecycle stage once.
I disagree. Scrum is better in a situation where
you can depend on the "players"; and,
the requirements might very well be changing underneath you.
A college type project generally has pretty good requirements AND the potential of flaky team members.
Further, you have to think about the purpose of even doing the project in that setting. The students need to think, plan, and discuss how things are going to work before they start diving in. Finally, scrum works best in a close knit, fast paced environment with constant communication. Which is unlikely to happen on a school assignment.
Scrum encourages a "let's just start" programming attitude which, again, is fine when you have experienced professionals working on it that through experience know the pitfalls to avoid up front.
No one says you have to fully implement SCRUM.
I can say from personal experience that SCRUM is great for 'amateurs' :) . At my 4th semester, we had to make a project in the scope of 4 months. Our group of 4 managed "semi-SCRUM" like this:
Sprints were of 2 weeks
No daily stand-up meetings (We were physically close, so we took everything on the fly)
All sprints had a headline from the start of the project. These were our milestones.
We had 2 weeks of buffer time, since we expected to delay :)
SCRUM itself is rather complex, but the ideas of sprints, part-deleverances, leadership and the likes are great. It doesn't really take more than a day for everyone to understand these concepts. For us, SCRUM made sure we had a top-notch project ready by the deadline, with tons of feedback during the development. Top grade too :)
There will always be some team dynamics to get worked out for how things like the daily stand-ups, storyboard and other Agile practices mature in a group. The big question to my mind is whether or not you have enough time to reap some of the benefits that comes after a few sprints and some rhythms have formed within a group. I would suggest at some point calling in someone more experienced with Scrum to give feedback about how to improve what you have as part of the methodology is to grow and evolve over time, IMO.
So, it is fine for you to use Scrum and see how it goes. After all, everyone has to get started somewhere and various modifications on the methodology are common to my mind. There is something to be said for how you'll walk the walk which may be easier or harder than you imagine. Good luck and I do realize this is echoing a lot of Ben's excellent answer.
I think your main problem is going to be in the estimation and tracking to the planned sprint duration. In the past, I’ve found that when resources are not intimately familiar with the coding environment they’ll be working in (this can happen with professionals adopting a new technology), it’s very easy for sprints to go off the rails. Task breakout estimation becomes guesswork and consequently it becomes very difficult to run sprints to plan.
Having said that, there are elements of Scrum which would be very useful in this environment; daily standup meetings and iterative releases are the ones that come immediately to mind. Personally, I don’t subscribe to the “do all of Scrum or you’re not doing Scrum” mantra. Be pragmatic in your approach and pick elements of the methodology which will work for you. Make sure you incorporate the continuous improvement component of doing sprint retrospectives so you can proceed with the assumption of refining and enhancing and you’ll be heading in the right direction.

Let's say that a developer is interested in learning Scrum, but nobody else on the team is interested. I realize that Scrum is made for teams, and the process would have to be modified to fit a single person.
Is there any benefit to be gained by the developer trying Scrum, even if the team doesn't? If so, how would the process be modified to suit the situation?
I think there's benefit to be gained by any method that helps you develop goals, tasks, keep on top of work and deliver something often.
Your individual work-products would gain the same advantages that teams gain with scrum:
You'd get something done every {Sprint Iteration Period Here}, something you can hand off and say "This is now ready".
Your estimation technique will start to improve with reflection and retrospectives
You'll start to plan your day and make commitments to yourself about getting things done, so again your estimation of your capacity will increase
Retrospectives will formalize improvement of your personal work process. You'll start actively improving, removing and adapting to suit you and your individual needs.
You wouldn't be able to rely on other team members to help out, which is a bit annoying, and you wouldn't have a product owner, Scrum master or a backlog to pick tasks from. You may not even be in a position to make decisions on what to work on next. But I think the formal discipline and reflection is helpful for all craft practitioners, at all levels, alone or in groups.
And who knows, you might even inspire your team to Scrum it up once they see what great results you're getting.
I would suggest that you use Extreme Programming instead, as that works better for one programming than a decidely team-based process.
Then you can get the benefits of being more agile, but if your team is not agile then you will have some issues due to the use of a different paradigm.
For me, the biggest key was getting buy-in from my supervisor. It can be tough to try and have some sort of Sprint only to have it interupted multiple times (Supposedly XP teams handle this better, but I don't think any developer does.). Also, don't forget to include either power users (they could be testers) or members of other departments that could be used as Product Owners. I like to sit with other users and do a type of paired programming (OK they don't code) where I can ask questions while coding and do quick demos to get feedback. This helps when I'm struggling to create specs because those requesting the app are having a hard time telling me what they want.
Even if it's just you in the daily stand-up, it can be scrum.
If you compare yesterday's planned with actual and define today's plans -- without talking to other people -- that's still a kind of daily stand-up.
I'd say that what you're doing probably is scrum if you're following the daily-sprint-release cycles; even if there aren't a any other people to talk to each morning.
G'day,
For the best thing to come out of learning Scrum is the concept of involving the customer early and often. That way there are no nasty "that's actually not what we wanted" moments when you deliver to the customer after six months hard work.
HTH

I'm the second dev and a recent hire here at a PHP/MySQL shop. I was hired mostly due to my experience in wrangling some sort of process out of a chaotic mess. At least, that's what I did at my last company. ;)
Since I've been here (a few months now), I've brought on board my boss, my product manager and several other key figures (But mostly chickens, if you pardon the Scrum-based stereotyping). I've also helped bring in some visibility to the development cycle of a major product that has been lagging for over a year. People are loving it!
However, my coworker (the only other dev here for now) is not into it. She prefers to close her door and focus on her work and be left alone. Me? I'm into the whole Agile approach of collaboration, cooperation and openness. Without her input, I started the Scrum practices (daily scrums, burndown charts and other things I've found that worked for me and my previous teams (ala H. Kniberg's cool wall chart). During our daily stand up she slinks by and ignores us as if we actually weren't standing right outside her door (we are actually). It's pretty amazing. I've never seen such resistance.
Question... how do I get her onboard? Peer pressure is not working.
Thanks from fellow Scrum-borg,
beaudetious
While Scrum other agile methodologies like it embody a lot of good practices, sometimes giving it a name and making it (as many bloggers have commented on) a "religion" that must be adopted in the workplace is rather offputting to a lot of people, including myself.
It depends on what your options and commitments are, but I know I'd be a lot more keen on accepting ideas because they are good ideas, not because they are a bandwagon. Try implementing/drawing her in to the practices one at a time, by showing her how they can improve her life and workflow as well.
Programmers love cool things that help them get stuff done. They hate being preached at or being asked to board what they see as a bandwagon. Present it as the former rather than the latter. (It goes without saying, make sure it actually IS the former)
Edit: another question
I've never actually worked for a place that used a specific agile methodology, though I'm pretty happy where I'm at now in that we incorporate a lot of agile practices without the hype and the dogma (best of both worlds, IMHO).
But I was just reading about Scrum and, is a system like that even beneficial for a 2 person team? Scrum does add a certain amount of overhead to a project, it seems, and that might outweigh the benefits when you have a very small team where communication and planning is already easy.
Without her input, I started the Scrum practices (daily scrums, burndown charts and other things I've found that worked for me and my previous teams (ala H. Kniberg's cool wall chart). During out daily stand up she slinks by and ignores us as if we actually weren't standing right outside her door (we are actually). It's pretty amazing. I've never seen such resistance.
Question... how do I get her onboard? Peer pressure is not working.
Yikes! Who would ever want to work in such an oppressive environment? If you're lucky, she's sending around her resume and you'll be able to hire someone who is on board with your development process.
Assuming you want to hang on to her, I'd turn down (or off) the rhetoric and work on being a friend and co-worker first. If the project is a year late, she can't be feeling good about herself and it sounds like you aren't afraid to trumpet your success. That can be intimidating.
I know nothing about Scrum, however. I'm just imagining what it would be like to walk around in your co-worker's shoes.
beaudetious, buddy,
I would really suggest you read Steve Yegge's blog called "Good Agile, Bad Agile". It's an oldy but a goody, and I think it's a must read for anyone - like myself about 2 months ago - who gets a little let's say "over-eager" to agile-up their workplace. Agile offers a lot of good practices, but you have to take them all with a grain of salt and adopt what you're lacking and skip out on all the other crud that might be unuseful for a particular situation - e.g. the daily scrum. If your co-worker would just like to code in quiet (read Peopleware for why this is a good thing) and she's being a productive team member quit bugging her with your scrumming a let her work in whatever way she likes most.
People are usually less "hostile" about these practices if you just approach them and simply say "Do you have a sec? Listen, communication is really a problem right now, I feel like I don't know what you're doing and I really don't want to step on your toes again and spend two days writing something you already did like last week, so let's work on this. I'd like to try X, what do you think?". Be compassionate and don't tolerate "bad apples", that's literally how I agiled up my workplace, and many problems have started evaporating. We're by no means an 100% XP or 100% Scrum compliant place, because we just use whatever works and was needed.
Simple. Don't talk about scrum. Don't use scrum on her. Instead take the underlying principles of scrum (e.g. the purpose as opposed to the application) and create different approaches that accommodate her way of working but have subtle tints of scrum.
All humans are different and a lot of programmers dislike scrum. I wouldn't force it upon them as that would just be counter-productive. I'd suggest identifying the problems in the development process (in a non-scrum fashion), see if you can get her to agree that the issues exist, then ask her what she thinks would be a good solution. Her co-operation and input into the process is essential to her co-operation, if she doesn't have buy-in she wont become a citizen.
From there on in you can hopefully create some sort of quasi-hybrid scrum + her approach to the process where you can both agree on the way forward.
I think the key would be to help her understand why you are doing Scrum in the first place. I guess you have your reasons, so why not tell her? You are likely to get resistance towards any change if the people involved don't understand why there is change or what they will benefit from it. If you can explain your reasons for using Scrum, and the following benefits, to her in a way that relates to her everyday work, I think she is more likely to adapt a more positive attitude towards it.
If she sees no value in the Scrum process, or doesn't understand how it relates to her, she probably won't care about it.
I think one of the most important concepts for someone to understand regarding Scrum is the fact that you are working as a group and commit to your project as a group, not as individuals. For many people, this is the hardest thing to grasp, since they are so used to living in "their own World".
I'm not sure Scrum is the central issue here; I'm guessing she feels threatened by the new guy bringing in a lot of new ideas and stirring things up. I've been in that situation before as the new person bringing in a new perspective on things, and sometimes it's just difficult to immediately bring those existing people around to a new way of thinking. It often requires a culture shift which doesn't happen overnight.
Try to get her input and opinion on things as much as possible, and try to show that you respect that she has been on the team longer than you. If after a while she still doesn't participate, then all you can do is mention it to your Manager and let them take it from there.
Continue your efforts to involve the other developer. Remember you are the one who wants to make this change. Ask for help with problems you have. Invite them to the daily stand up meeting. I currently do the planning for the daily stand up and I make sure all the pigs and chickens are invited. If you are the lead on the project it is up to you to address the situation and take a risk. Put yourself out there.
