Thanks to one of our users from Washington State’s Administrative Office of the Courts for pointing this out: it turned out that the count of “remaining” cards in the Board Summary was including items that were in the Trash, which was misleading.
This has now been fixed: the count shown in the Board Summary gives you a better idea of what work remains.
To access the Board Summary on any Task Board or Scrum Board, click on the Board Summary button shown on the top-right of the Kerika app:
Board Settings is highlighted
Clicking on this button will show a summary of the board, like in this example:
Remaining work
In the example above, the count of “28 items remain” now properly excludes any items that are in the board’s Trash.
Interested in using Kerika for software development? Here’s a practical example, taken from one of our own boards, that highlights best practices for tracking, investigating and fixing bugs.
First, a look at our Workflow
Every software development team will want to set up its own workflow, of course, reflecting its internal dynamics and available resources. Here’s the Scrum Board workflow we use in our team:
Scrum Workflow
Our Scrum Boards are organized with these columns:
The Backlog contains all the ideas, large and small, that we have on our product road map: in Scrum terminology, it’s our Product Backlog.
The Sprint Backlog is the set of cards that we pulled from the Backlog at the start of this Sprint: right now, only 4 items are left as we are close to the end of our 2-week Sprint Cycle.
Within each Sprint, cards are picked up developers and first moved into the Planning column, where detailed analysis of the work to be done is completed.
Depending upon the complexity of a particular work item, a developer may request a design review before moving the card further into the Development column.
Developers do their own unit testing as part of the Development phase, but then the work item moves further down to the the QA column which frequently includes formal code review. (More on that below…)
After a bug has been fixed, had its code reviewed and passed unit testing, it gets Deployed to the Testenvironment.
We usually wait until the 2-week Sprint is over before asking the entire team to present the entire Sprint’s output to the Product Owner for the Show & Tell; this avoids distracting the team midway through the Sprint.
Once the output of a Sprint has passed the Show & Tell, it can then be Deployed toProduction.
The Done column shows all the work that got done in this Sprint. That’s where all cards are supposed to go, but sometimes a work item is abandoned and moved to the Trash.
(Side note: we sometimes use WIP Limits to make sure that people are not over-committed to work, but this is not a consistent practice within our team.)
Logging the bug
Now, let’s take a look at an example of an actual bug card that was worked on by our team:
Example of a bug tracked as a Kerika card
(This particular bug doesn’t have a lot in the details, because it is related to another task that is currently underway, and Kerika makes it easy to link cards, canvases or boards.)
Some bugs go into the Product Backlog, if they are not considered especially urgent, but others go straight into the Sprint Backlog if they represent serious production problems that might affect user’s access or the reliability of their data.
Adding bugs to the Product Backlog lets us process bugs along with other development, e.g. of new features, in the same way: everything can be prioritized by the Product Owner and handled through a consistent workflow.
Documenting the bug
Our bug reports typically come with two attachments; at least one of these should always be included so that the developer has a clear starting point for her work:
A screenshot showing the user experience (if the bug can be observed directly by the user.)
An excerpt from the error log, if the server reported any errors around the time the bug was observed.
Original bug report documents
Kerika makes it easy to attach any kind of content to any card, canvas or board: for bug fixing, particularly in the analysis phase, this is very useful if the user needs to include URLs, material from Sourceforge or similar sites, links to Github, etc.
Repro, Cause & Fix
Before any bug is fixed, our developers always add a standard document we call Repro, Cause and Fix as an attachment to the card:
Repro, Cause and Fix
This document is added no matter how trivial the bug.
Why? Because, on average our team goes through about 30-40 cards a week, and has been doing so for years now. If we don’t document our analysis now, we will never recall our logic in the future.
Repro, Cause and Fix
Our team adopts a consistent layout of the Repro, Cause & Fix document, which we adhere to even for trivial bugs:
The Repro Steps are the steps needed to trigger the bug: usually they consist of a specific sequence of actions taken by a user that cause the bug to appear, but they can also consist of a sequence of events in the background, like specific server activity or memory/CPU utilization conditions, or overall network traffic, that trigger the bug.
The Expected Behavior helps clarify the developer’s understanding of the how the software should behave in this situation. It’s not uncommon for a developer who is new to the team to misunderstand how a particular feature is expected to behave, which could lead to more bugs being introduced. Clarifying Expected Behavior in this document provides an easy way for the Product Owner and the Team Lead to confirm that the developer is not going to go down the wrong track.
Introduced Since: our developers try to pinpoint the specific point in the software’s life where the bug was introduced. This helps the developers reflect upon how errors are created in the first place: the blind spots lie in their analytical patterns that need to be strengthened.
(In this particular example, the developer has been able to point back to some of her own work on an earlier feature implementation that caused this bug to appear.)
Root Cause is not the same as the Repro Steps. While a specific sequence of actions or events may reliably display the effects of a particular bug, they only provide the starting point for the analysis; the Root Cause itself is discovered only when the developer examines the code in detail and determines exactly what is breaking.
Affected Feature: all of our code goes through code review, which we view as one of the most effective QA processes we could adopt, but it can be very challenging when you are processing 30 cards each week, each affecting a different part of the software.
Identifying the Affected Feature helps with the code review process, since the reviewer can consider the bug fix in the larger context of the feature that’s being modified. Without this, it is doubtful that we could review so many changes each week.
Affected User: in most cases, this is “everyone” we offer the same Kerika to all our users, whether they are on free trials or have paid for professional subscriptions.
Identifying Affected Users is useful, nonetheless, when dealing with bugs that are browser-specific, or service-specific: for example, determining that a particular bug affects only Kerika+Google users, or only Internet Explorer users.
The Fix: OK, this might seem obvious, but this section really refers to identifying the specific modules in the software that will be changed as a result of the bug fix being applied.
Like many others, we use Git for managing our source code — along with Maven for builds — since our server environment is all Java-based.
The Fix
The Fix section usually includes references to Git checkins: this helps with future bug fixes, by making it easy to traceback sources of new bugs — part of the Introduced Since section described above.
We use separate Git branches for each feature that we develop so that we can decide precisely what gets released to production, and what is held back for future work.
This helps with the Show & Tell phase of our workflow, when the developers demonstrate the output of the Sprint to the Product Owner, who has the option to accept or reject specific features (i.e. cards on the Scrum Board).
Code Review
All of our code goes through code review, no matter how trivial the change:
Code review
We really believe that code reviews are one of the most effective QA practices we could adopt: having a second pair of eyes look over code can very considerably reduce the chances of new bugs being introduced.
So…
Kerika is great for distributed software teams: our own team is spread out between Seattle and India (roughly 10,000 miles apart!), and all of our work is done using Kerika for task management, content management and team collaboration.
Of course, an added benefit of “eating our own dogfood” is that we are highly motivated to make sure Kerika is the best tool there is for distributed teams :-)
Kerika helps you (and your team) manage multiple versions of a document, and it does this so smoothly that you might not even have noticed…
Here’s how it works: when you add a file to a Kerika card or canvas, it shows up in the list of attachments, like this:
File attached to a card
If you then attach another file to the same card or canvas that has the same name and file type, Kerika automatically treats it as a new version of the same file, rather than a completely different file:
Uploading a new version
In the example above, when a Team Member adds another document called Foo.docx to a card that already has a file attached to it with the same name and file type, Kerika treats the new document as a new version of the old Foo.docx rather than as two documents called Foo.docx.
How you access all these old versions depends upon how you set up your Kerika account:
If you are using Kerika+Google, these files are being stored in your Google Drive, and Google will manage the versions for you: you can find this under the File menu in Google Docs
Google Docs versions
And pretty much the same thing is true if you are using Kerika+Box: Box will take care of the older versions automatically, although their user interface is slightly different
Box version history
And what if you signed up directly with Kerika, without using a Google or Box ID?
We provide an easy way to get to older versions of a file for users who signed up directly: when you are previewing a file, click on the Older versions of this file link on the top-right.
File preview
Kerika will show you a list of all the old versions that are available for that file, along with details on who uploaded those versions, and when:

Did you know that we have made it really easy to download files that you attach to a Kerika card, canvas or board?
Just hover your mouse over an attachment, and you will see these buttons appear on the right:
Downloading attachments
These buttons let you:
Download a file
Rename a file
Delete a file attachment
Couple of other points to note:
Rename a file shows off our integration with Google Drive (for our Kerika+Google users) and with Box’s service (for our Kerika+Box users): renaming the file from inside Kerika will automatically rename it in your Google Drive or Box folder as well.
Deleting a file attachment doesn’t actually delete the file from your Google Drive or Box account: it just means that file is no longer attached to that particular Kerika card, canvas or board.
When you sign up directly with Kerika, we take a look at your email address and try to figure out whether you would be better off with Kerika+Google or Kerika+Box.
This helps ensure that you are going to be able to easily collaborate with other people from your company, who may have signed up already using their Google or Box IDs.
Here’s an example: joe@kerika.com tries to sign up directly, and we suggest automatically that he sign up as a Kerika+Box user since so many of his colleagues already have Kerika+Box accounts:
If you are using Kerika+Box, we store your Kerika files in your Box account: you can always go to Box.com, login using your Box ID, and see for yourself.
(But, please, don’t move them around!)
What you might notice is that the filenames in Box have some random characters appended to them. For example, a file that you might see listed inside Kerika as “Alternative Home Page” actually shows up with some random characters appended, like this:
URL appended to file names
The reason we do this with files we store in Box — and not for files we store in Google Drive, for our Kerika+Google users, is that Box doesn’t allow for several files within a single folder to have the same name.
(Google does, which is why we don’t need to append any random characters to the files we store in Google Drive.)
It’s very common for our users to have several files within the same board that have the same name: for example, our developers always attach an analysis document to each card that describes exactly what they are doing. (Yes, we are fairly fanatical about documenting our software!)
These documents are often the same for many cards: Analysis.docx or Results.xlsx or Mockup.png might show up hundreds of times within a single board.
Since all the files related to a single Kerika board are stored in the same folder in your Box account, this presents a problem: Box won’t allow for more than one file called Analysis.docx within a folder.
We get around this limitation by appending these random characters, so that effectively every Analysis.docx file has a unique name.
But, we also try to avoid confusing our users, so when we show a list of files attached to a card, we strip out the random characters:
Displaying files as attachments
And the same goes for downloading files: we strip out the random characters and give you a clean-looking file.
It’s not that we have sensitive stuff on the blog: quite the contrary. It’s just that we have implemented HTTP Strict Transport Security (HSTS) across the entire kerika.com domain.
It allows web servers to declare that web browsers should only interact with it using secure HTTPS connections, and never via the insecure HTTP protocol.
Since our blog is on a sub-domain of kerika (blog.kerika.com, to be precise), we needed to implement SSL and HTTPS for the blog as well.
Some advice to fellow developers: don’t be tempted to use a local snapshot of a rapidly evolving library, like Polymer.
One of our team members was doing this because he thought it would hasten his compilation when he needed to do new builds of Kerika (he is located in an area with somewhat slow Internet connections).
This might, sort of, work with a very stable library, but with something that is evolving fairly rapidly (like Polymer), you run the far greater risk that you snapshot’ed a somewhat buggy version.
That’s what happened to us, leading to a perplexing day of debugging: we had a version of Polymer that didn’t work well with Internet Explorer 11.
Just our luck that our developer took a snapshot of that particular build and then kept it on his local machine…
