Scrum Overview Diagram

February 27, 2012 6 comments

It is challenging to find a good, high-level summary of Scrum that you can share with your team.  One that visually describes the core concepts of the methodology in a way that anybody can understand. After having produced the new Scrum in 10 Minutes video, we decided to take a stab at this using the visuals from the video. What do you think?

New Scrum in Under 10 Minutes Video

Shane the Videographer

Late last year, I felt it was about time to update the now 3-year old “Scrum in Under 10 Minutes” video. The video has been immensely popular having been viewed over 600,000 times. In that time I have received a tremendous amount of great feedback for improvements to the video. I had a few ideas of my own too, so I wanted to see if we could redo the video and still keep it under 10 minutes.

For nearly a year I’ve also had the pleasure of working with Shane, Axosoft’s resident videographer. Shane is an amazing artist and he helped make the new scrum video visually unbelievable. We’ve been working on the new version of the video for nearly 3 months (actually mostly Shane has been working on it and I just keep bugging him), and it’s finally ready for its debut.

Here it is:

Earlier this month we spent a few days in Utah at the Agile 2011 conference as “Gold Sponsors” of the event. It was a very fun show. We met a lot of great people and gave demos of the new user experience of OnTime 11. We also gave away quite a bit of swag, including these popular Tego Audio Portable Speakers.

Here is a quick video compilation of the highlights:

Scrum Planning Board on the iPad

February 1, 2010 13 comments

We thought it would be fun to imagine what the OnTime V10 Scrum Planning Board (a.k.a. task board) would look like when used through the iPad:

The touch interface of being able to drag-and-drop cards from one workflow step to another is going to absolutely rock on the iPad. I need to get my hands on one of these things asap! :-)

Scrum on Demand – Getting Started with Scrum

October 6, 2009 6 comments

So you are sold on Scrum, but having a hard time getting started, right? There are a lot of questions on your mind:

  • How do I convince the team to use Scrum?
  • How long should our sprints be?
  • How should we handle bugs?
  • What if our estimates are not accurate?
  • How do we handle items with dependencies across sprints?
  • What tool should we use to track everything?
  • How do I get my team trained on Scrum?

We’ll tackle each of these questions in this article.

How do I convince my team to use Scrum?

Remember that “using Scrum” mostly means the following things:

  1. Making a list of things that you need to get done for the project (product backlog)
  2. Prioritizing that list
  3. Estimating how long each item in the list will take
  4. Meeting regularly to see the status of items and make small adjustments
  5. Keep track of how much work remains until the project is finished (burndown chart)

So if you are getting any push-back from your team, management or executives on using Scrum, then don’t refer to it as Scrum. Come in with a plan that says you want to do the 5 things listed above. The resistance will immediately dissipate because there will no longer be a fear of the unknown. It’s hard to argue that “making a list of things we need to get done” is a bad thing. You’ll know it as the product backlog, but who cares if others call it that?

How long should our sprints be?

As a general rule of thumb, most dev teams have a typical “release cycle”. My standard recommendation is that make sure you fit at least 4 sprints to as many as 12 sprints into your release cycles. So if your typical release cycle is once every 6 months, it wouldn’t be a bad idea to have 6 sprints of 30-days each. On the other hand, if your release cycle is only 3 months, you still might want 6 sprints, but make them 2 weeks each.

How should we handle bugs?

There are two types of bugs. There are those that A) appear while you’re still working on a given feature PRIOR to the completion of the feature and B) bugs that are identified AFTER a feature is considered feature-complete. Bugs that are identified PRIOR to the feature being completed should be dealt with right away and the feature should never see the light of day without the bugs being addressed. However, the challenging part of bugs is how to deal with the bugs that are identified AFTER the feature is completed and released in the product.

There are two main schools of thought here. Neither is better than the other. Use the one that fits your team best. Here they are:

  1. Log bugs just like any other product backlog item and in each sprint, take a handful of bugs to address in each sprint. In this scenario, bugs and features are thrown into the same product backlog and prioritized, estimated and dealt with just like any other product backlog item.
  2. The other school of thought is to track bugs in a separate “Defects Backlog” and have dedicated sprints that focus on nothing but bugs to help everyone stay focused on creating the most stable product. The idea here is that with everyone in the team focused on fixed bugs, nobody is busy introducing new bugs by coding new features and as a result, the team will produce a more polished product.

How do we create more accurate estimates?

The first thing to remember is that nobody creates accurate estimates. The key is to create an accurate overall target release date that is manageable. So there are some best practice rules on creating better estimates. Here they are:

  1. Involve at least 2-3 of your most experience engineers on creating estimates, along with the person who will ultimately be responsible for coding it. Take the higher estimate value if the group doesn’t agree.
  2. Keep estimates at approximate values that are thrown into larger buckets. For example, your “estimate values” might be:
    • 1 Hour
    • 2 Hours
    • 4 Hours
    • 8 Hours
    • 2 Days
    • 3 Days
    • 5 Days
    • 2 Weeks
    • 3 Weeks
  3. If an item is estimated to take 10 minutes, that falls into the 1-hour bucket. If it’s estimated to take 3 or 4 hours, that probably falls into the 8 hour bucket. Being conservative with estimates will address some of the unavoidable down-time for estimations.
  4. Expect no more than 6 hours of productivity each day from each software engineer. That means the typical software engineer should plow through 30 hours of estimated work per week. Don’t expect more because they have overhead of meetings, checking email and Facebook!
  5. Lastly, be sure to leave room in your overall schedule for unforeseen items, changes that will inevitably be made and other things that you simply can not predict. Generally speaking, you’ll want about 1 week of padding for each month of development. So on a 4 month project, don’t take on more than 3 months worth of work.

How do we handle items with dependencies across sprints?

Dependent and complex items are essentially the high-risk items in software development projects. To minimize the risk, there are two things you can do:

  1. Use Proof-of-Concept prototypes as often as possible. These throw-away projects should help demonstrate the feasibility of high-risk items. These items include anything that the team does not have experience developing, which might include a new cool User Interface design, back end data storage, cool new web interface and so on.
  2. Tackle the tough tasks in your first few sprints. This will help you identify problems early. You don’t want to find out two weeks prior to your ship-date that a task that was expected to take a couple of weeks will in fact take a couple of months. Putting high-risk items first, will help you get project visibility early that will allow you to change things up to address your timeline.

What Scrum tool should we use to track everything?

It’s always surprising when I find software development teams that still use Excel or even sticky notes, paper and white boards to manage the development of a software project. After all, we are all in the business of creating software that makes some manual tasks easier. There are dozens of software applications out there that are far superior to using Excel or an offline solution.

One example of such a tool (my favorite, in fact :-), is my company’s product, Axosoft OnTime. OnTime is designed to stay out of the way of software developers so they can focus on writing code, which is what software developers do best. But it also provides project managers, scrum masters and executives with all of the project visibility tools that are instrumental in helping them make decisions about the direction of the project.

Here is how OnTime helps Scrum teams:

The Product Backlog

Scrum Product BacklogsOnTime allows for Scrum teams to manage their product backlog in either of two ways:

  • Single Backlog for Everything – The ability to see everything that relates to a given product, version or sprint in a single product backlog is a nice way to view project information. It allows teams to deal with bugs in the same way they deal with any other requirements.
  • Separate Backlogs for Defects (Bugs) and Features (Requirements) – OnTime also allows teams to separate defects, features and tasks into independent backlogs. This level of flexibility allows for each type of item to have a separate workflow, allowing defects to go through a different process than feature requests. For example, a defect might need to be verified, while a feature requests first needs approval.

Regardless of which way you decide to go with the product backlog, OnTime provides powerful backlog features that are useful for every user, including:

  • Ability to create public and private backlog filters with powerful AND/OR functionality for combining conditions
  • Ability to group backlog items to view them by assignee, status, workflow step or any other built-in or custom field
  • Ability to create saved public or private views which save everything from fields being displayed, the sizes of each column, filter conditions and more
  • Ability to set first, second and even third sort criteria so that you can view your backlog in the way that makes most sense
  • Ability to apply a change (such as status, workflow, date or other changes) to multiple items with the click of just 1 button

These features make OnTime one of the most powerful tools on the market for Scrum teams who need fine controls on their product backlog management.

Sprint Planning

Scrum Sprint PlanningSprint planning is one of the most important activities that Scrum-based teams perform. With OnTime, sprint planning takes form naturally from the product backlog. Assigning items to a sprint is as easy as dragging and dropping (in the OnTime Windows client) any number of items from your product backlog onto a planned sprint. Alternatively, you can use the multi-edit feature to assign a number of product backlog items to any given sprint.

To create the planned sprints, OnTime also makes the Scrum Master’s job easy. The OnTime Releases hierarchy breaks projects in the following way:

  • Products – You can manage any number of products in OnTime
    • Versions – Each Product can have any number of versions
      • Sprints – Each Version has numerous Sprints

OnTime also provide auto-calculators for sprint start and end dates. You simply tell the system how many days your typical sprint is and OnTime will automatically calculate the dates.

Daily Standups

All meetings are overhead. With that in mind, the goal of meetings should be to keep them as short as possible (and as Einstein might say, “but no shorter!”). OnTime facilitates meetings, such as the Scrum Daily Standup, by having all the information that’s needed to make decisions ready at hand. A typical meeting starts in a conference room with the main OnTime screen being projected on a screen with a “Daily Standup” Previously Saved View applied to the system to show only the items of focus for the given sprint.

The team has the ability to go through the items right there, make notes, change status and so on, allowing the meeting’s decisions to be captured in real-time without further work that would typically be assigned to the Scrum Master.

Tracking Progress (Burndown Charts)

OnTime Burndown ChartsIf you don’t track it, there is no way to improve it. Furthermore, project visibility is perhaps the most important factor for project success. That’s where Scrum burn-down charts play a pivotal role to making sure projects are on track and OnTime provides an extensive set of capabilities when it comes to Project Visibility and Burn-down charts, including:

  • View a mini burndown chart on the main OnTime page, giving everybody on the team the same sense of urgency to move the project in the right direction
  • Multiple burndown charts depicting one or more sprints, versions or products in a fully customizable Charts Dashboard
  • View rollups of burndown charts for multiple sprints for a given version of a product
  • Show trend (such as the burndown velocity) and project a ship-date for a given version or completion date of a sprint

The OnTime dashboard provides a number of other useful charts too, like the Treemap, or Trend Reports and even user workloads to make sure you are not overloading a particular team member with too much work.

Project Management on Demand: OnTime Now!

September 24, 2009 3 comments

How do you make an already great project-management on demand system better than ever? How about improving the performance by as much as 500%?

Here is how we did it…

A Little Background

Ever since the introduction of OnTime V2.0, Axosoft has provided a hosted option.  This allows teams that want to get going with OnTime right away the option to do so without having to setup their own installations. We expected this option to be extremely popular, but to our surprise, over the past 6 years, relatively few of our customers have chosen to go the “Software as a Service” route.

Don’t get me wrong, “relatively few” still means hundreds of customers, but we were expecting thousands.

So a few months back, we decided to deep-dive into the numbers and figure out what was going on. What we found was that the closer customers were to Axosoft’s physical data center location, the more likely they were to choose the hosted service.

Hmmm…that seemed odd.

So we did a bit more digging with the help of some external resources to see what the OnTime Hosted user experience was like from different parts of the world.

The results were shocking!

Depending on customers’ locations and bandwidth (with respect to Axosoft’s Tempe, Arizona data center), the performance they experienced could vary by as much as 500% over optimum performance. This was especially true for our European and Australian customers. That meant that an OnTime page that might have taken 1 second to load under normal circumstances might take as much as 5 seconds to load for some customers.

Clearly unacceptable.

The problem, of course, is not an easy problem to solve. Because regardless of how well connected our data center is, we are also bound by customers’ connections — and all of the connections in between. The longer the distance and the more hops between a customer and OnTime Hosted, the worse the performance.

So we focused our entire IT and product engineering team on solving this problem.

Introducing ‘OnTime Now!’

OnTime Now! takes all of the great OnTime features, usability and innovation, and wraps it up in a hosted environment that allows customers to be up and running in no time flat. But it has a unique twist:

YOU get to choose the data center where your OnTime Now is installed from 6 world-wide locations:

OnTime Now! Data Center Locations

The OnTime Now! Data Center locations are:

  • Tempe, Arizona (this is where all OnTime hosted customers were until now)
  • San Jose, California
  • San Antonio, Texas
  • Herndon, Virgina
  • London, United Kingdom
  • Brisbane, Australia

During the OnTime Now! signup process, you now get to choose the data center that will house your hosted account. To make the decision easier, we created a speed test, allowing you to choose the best performing site:

Bandwidth Tests
Bandwidth tests from Axosoft headquarters in Scottsdale, Arizona

Once a data center is selected, OnTime Now! goes to work immediately creating the DNS entries for your chosen URL, a brand new OnTime database, your own OnTime Web Server, Customer Portal Server, Remote Server, iPhone Server, SDK and everything you need for your OnTime installation to go live. The entire process takes only seconds, and then you receive an email with instructions on how to get started. It’s pretty amazing.

So How Much Better is it?

While nearly every customer outside of Arizona will see a performance improvement, the most drastic performance increases will be seen by our East Coast (US), European and Australian customers. The chart below shows the relative performance that a typical European customer would experience. The Blue bars show the relative speed to our Tempe, Arizona data center while the Red bars show the performance those same customers can expect from our London, UK data center (shorter bars are better). As you can see, the difference is incredible:

OnTimeNowEuroPerf2
OnTime Now! Performance from European Countries to Arizona and UK Data Centers

We’ve made a ton of other improvements too, but all of them pale in comparison to this one major improvement with performance.

Existing OnTime Hosted customers can expect to be contacted soon regarding these changes so we can transition existing customers to OnTime Now! and the data centers of their choosing.

Unprecedented Innovation

Our multiple data center strategy, which allows customers to choose the best performing data center is unprecedented in our industry. It required an enormous amount of effort to execute, not only in identifying and setting up servers in remote data centers across the globe, but also:

  • engineering new systems to manage these remote installations from a single location
  • allowing customers to seamlessly sign up and choose which data center to use for their OnTime installation
  • tying all this into Axosoft’s unique purchasing system (the Axosoft Online Store)
  • giving customer control of their system through the OnTime Now! Customer Dashboard

This was an awesome challenge!

Axosoft is truly blessed with some of the most incredibly talented people I know in this industry. No matter what challenges I throw at them, they seem to come up with solutions that shine.

Now, we’re back to the drawing board, coming up with the next big set of innovations that will move our industry forward. It’s fun doing unprecedented things. Stay tuned…
