The Perfect Agile Tool doesn’t yet exist. In my training and consulting work, I often have strong words to say about electronic tools. Most of the tools out there are really bad. Unfortunately, JIRA, the most common tool, is also the worst that I know of. (Actually, the only tool worse than JIRA for an Agile team is MS Project – which is just plain evil). Some Agile tools do a bit better, but most fall far short of a good physical task board (information radiator). I am often asked to evaluate and / or partner with tool vendors to “bless” their products. Here is what I am looking for before I will consider an outright endorsement of such a tool.
Features for a Perfect Agile Tool
This list is roughly organized in order of features which do show up in some tools to those which I have never seen or heard of in tools.
1. Skeumorphism: Cards and Wall
The tool should display the current work of an Agile team in a way that is immediately recognizable as a set of note cards or PostIt’s on a physical wall. This includes colours, sizes, etc. Most people will type to enter data so fonts should be chosen to mimic hand-printed letters. Every aspect of the display should remind people of the physical analogue of the tool.
2. Live Update
As team members are using the tool, all updates that they make should be visible as immediate updates to all the other team members including typing, moving cards around, etc. There is no off-line mode for the tool. In fact, if the tool is not receiving live updates, it should be clearly disabled so that the team member knows there is a problem with the information they have displayed.
3. Simple or No Access Control
Most Agile methods strongly de-emphaisize or even disallow traditional roles and encourage self-organizing teams. This means that fine-grained access control to different features of the tool should be eschewed in favour of extremely simple access control: everyone can do anything with the tool. (It actually helps if there is no “undo” feature, just like there’s no easy way to erase Sharpie written on a note card.)
4. Infinite Zoom In/Out
When you are using cards on a wall, it is easy to see the whole wall or to get up close and see even very fine details on a single note card. Although it does not have to be literally infinite, the wide and tight zoom levels in the tool should be at least a few orders of magnitude difference. As well, the zoom feature should be extremely easy to use, similar perhaps to the way that Google Maps functions. Among all the other features I mention, this is one of the top three in importance for the perfect Agile tool.
5. Touch Device Compatible
This seems like a super-obvious feature in this day and age of tablets, smart phones and touch-screen laptops. And it would take the cards on the wall metaphor just that extra little way. But very few tools are actually easy to use on touch devices. Dragging cards around and pinch to zoom are the obvious aspects of this feature. But nice finger-drawing features would also be a big plus (see below)!
6. Size Limit on Cards
For techies, this one is extremely counter-intuitive: limit the amount of information that can be stored on a “card” by the size of the card. It shouldn’t be possible to attach documents, screen shots, and tons of meta-data to a single card. Agile methods encourage time-boxing (e.g. Sprints), work-boxing (e.g. Work-in-Process limits), and space-boxing (e.g. team rooms). This principle of putting boundaries around an environment should apply to the information stored on a card. Information-boxing forces us to be succinct and to prefer face-to-face communication over written communication. Among all the other features I mention, this is one of the top three in importance for the perfect Agile tool.
7. Minimal Meta-Data
Information-boxing also applies to meta-data. Cards should not be associated with users in the system. Cards should not have lots of numerical information. Cards should not have associations with other cards such as parent-child or container-contained. Cards should not store “state” information except in extremely limited ways. At most, the electronic tool could store a card ID, card creation and removal time-stamps, and an association with either an Agile team or a product or project.
8. Overlapping Cards
Almost every electronic tool for Agile teams puts cards in columns. Get rid of the columns, and allow cards to overlap. If there is any “modal” behaviour in the tool, it would be to allow a team member to select and view a small collection of cards by de-overlapping them temporarily. Overlapping allows the creation of visually interesting and useful relationships between cards. Cards can be used to demarcate columns or groupings without enforcing strict in/out membership in a process step.
9. Rotatable, Foldable, Rip-able Cards
Increase the fidelity of the metaphor with physical cards on a wall. Rotation, folding and ripping are all useful idioms for creating distinct visual cues in physical cards. For example, one team might rotate cards 45 degrees to indicate that work is blocked on that card. Or another team might fold a dog-ear on a card to indicate it is in-progress. Or another team might rip cards to show they are complete. The flexibility of physical cards needs to be replicated in the electronic environment to allow a team to create its own visual idioms. Among all the other features I mention, this is one of the top three in importance for the perfect Agile tool.
10. Easy Sketching on Cards… Including the Back
Cards should allow free-form drawing with colours and some basic diagramming shapes (e.g. circles, squares, lines). Don’t make it a full diagramming canvas! Instead, allow team members to easily sketch layouts, UML, or state diagrams, or even memory aides. The back side of the card is often the best place for more “complex” sketches, but don’t let the zoom feature allow for arbitrarily detailed drawing. Lines need a minimum thickness to prevent excessive information storage on the cards.
11. Handwriting Recognition
With Siri and other voice-recognition systems, isn’t it time we also built in handwriting recognition? Allowing a team member to toggle between the handwriting view and the “OCR” view would often help with understanding. Allow it to be bi-directional so that the tool can “write” in the style of each of the team members so that text entry can be keyboard or finger/stylus.
12. Sync Between Wall and Electronic Tool
This is the most interesting feature: allow a photo of cards on a wall to be intelligently mapped to cards in an electronic tool (including creating new cards) and for the electronic tool to easily print on physical note cards for placement on a wall. There is all sorts of complexity to this feature including image recognition and a possible hardware requirement for a printer that can handle very small paper sizes (not common!)
These are the features that many electronic tools implement as part of being “enterprise-ready”. I’ll be brief on these points:
No Individual Tracking – the team matters, not who does what.
No Dependency Management – teams break dependencies, tools don’t manage dependencies.
No Time Tracking – bums in seats typing doesn’t matter: “the primary measure of progress is working software” (or whatever valuable thing the team is building) – from the Agile Manifesto.
No Actuals vs. Estimates – we’re all bad at predicting the future so don’t bother with trying to get better.
No Report Generation – managers and leaders should come and see real results and interact directly with the team (also, statistics lie).
No Integration Points – this is the worst of the anti-features since it is the one that leads to the most anti-agile creeping featuritis. Remember: “Individuals and interactions [are valued] over processes and tools” – from the Agile Manifesto.
Evaluation of Common Agile Tools
I go from “Good” to “Bad” with two special categories that are discontinuous from the normal scale: “Ideal” and “Evil”. I think of tools as falling somewhere on this scale, but I acknowledge that these tools are evolving products and this diagram may not reflect current reality. The scale looks like this, with a few examples put on the scale:
Plea for the Perfect Agile Tool
I still hope that some day someone will build the perfect Agile tool. I’ve seen many of the ideal features listed above in other innovative non-Agile tools. For example, 3M made a PostIt® Plus tool for the iPhone that does some really cool stuff. There’s other tools that do handwriting recognition, etc. Putting it all together in a super-user-friendly package would really get me excited.
Let me know if you think you know of a tool that gets close to the ideal – I would be happy to check it out and provide feedback / commentary!
