Scrum on Demand – Getting Started with Scrum

Posted by Tara Hamilton-Whitaker on October 12, 2009

I feel honoured to share an article written by Hamid Shojaee, CEO of Axosoft. Hamid is the creator of the most viewed Scrum video on the web – Scrum in 10 Minutes and is, quite frankly, rather clued up!

Here, he shares a few of his pearls of wisdom…

Enjoy!

By: Hamid Shojaee

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:

  1. Appear while you’re still working on a given feature PRIOR to the completion of the feature and
  2. 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

OnTime allows for Scrum teams to manage their product backlog in either of two ways:ss_scrum_backlog

  • 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

ss_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)

ss_scrum_burndownIf 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.

It’s Scrum On-Demand

OTNow_saas01With Axosoft’s OnTime Now! Scrum teams can actually signup for and start using a 30-day, 10-user trial of the OnTime system in seconds! Axosoft has done an incredible amount of work to make the OnTime Now! system exceptionally unique with the following features:

It’s Inside of Your IDE (Visual Studio & Eclipse)

eclipse_plugin_win_mac_linuxDesigned to stay out of the way, OnTime provides the ability for developers to stay in the environment where they are most productive: The development IDE. OnTime supports both Visual Studio and Eclipse and allows developers to access the information they need right at their fingertips. The Visual Studio and Eclipse plugins allow users to:

  • Add, Edit and modify the workflow or status of items directly in the Eclipse and VS IDEs
  • Filter, sort and view items in a variety of ways
  • Add notes, attachments and work log entries for items
  • View items associated to a product, version or sprint

For developers, nothing is more productive than being able to stay in the IDE while modifying project management related tasks

It’s Even in Your iPhone

iphone_main_medData was meant to be shared and viewed from everywhere. That’s why OnTime provides every team member with the ability to access their OnTime system from the convenience of their iPhone. The OnTime iPhone client provides some powerful features, including:

  • View and edit all item types (defects, features, tasks and incidents)
  • Filter and sort the product backlog(s)
  • View items by project, product, version or sprint
  • Add attachments, notes and comments to items
  • Log work done on a given item
  • View a number of built-in charts or create custom charts meeting any filter criteria

The OnTime iPhone client is intuitive and powerful.

How do I get my team trained on Scrum tools?

The last piece of the puzzle is how do you get your team trained on the tool that you select? Axosoft has a solution for that too. In fact, Axosoft offers a number of FREE Web-Based, Instructor-Lead classes on the following subjects:

  • Implementing Agile / Scrum Methods with OnTime (Class code OT-302) – This hour-long class walks you through how to setup an OnTime database to use Agile or Scrum terminology, setup product backlogs and get going with burndown charts.

The Rise and Rise of Pointless Project Planning…!

Posted by Tara Hamilton-Whitaker on October 2, 2009

It goes without saying that every project plan, business or product strategy is constructed off the back of a vast series of assumptions.

So, if assumptions are so important and usefull… then why do they get such negative press? E.g.

  • “Assumptions make an ASS [out of] U [and] ME”
  • “Assumption is the mother of all f*** ups”

The problem is people often cut corners when making assumptions… or base plans on assumptions that have no grounding in reality.  This is a big problem.

So, why do people waste their time building plans around totally unrealistic assumptions?

I can see a few reasons why:

  • To prove or illustrate a point
  • To compare a best case and/or worst case scenario with a more realistic option

And we must not forget (controversial but true)…

  • Inexperience
  • Denial
  • Laziness

One more (which seems to be really common!)…

  • Fear of conveying the ‘truth’

Now, please don’t get me wrong. I have no problem (usually!) with plans that are created with the best of intention, best of effort and turn out to be totally incorrect.  In fact, I embrace change… which is one of the reasons why I am an advocate of Agile working practices.

With that said, I do have a problem with plans being created and published that are based upon a series of assumptions that the creator believes are unrealistic.

It truly amazes me how often plans are created simply to pacify a Product Owner e.g. it will take five months, the PO wants it to take two months (without increasing investment or compromising quality)… so the plan is built to *look like* everything will be completed within two months…

What is the point!?

It will only take a matter of weeks for everyone to unveil the ‘truth’… At this point, both the person who created the plan and the Product Owner will lose credibility

One of the biggest challenges for a project manager is to deliver bad news in a positive way.  I admit that this is not always easy.

If you find yourself in the situation described above i.e. your Product Owner wants you become a magician, then consider the following before you give up or decide to fabricate a plan…

Few things are impossible… – most things have a price. The question boils down to whether or not you can afford the price (whether it be measured in monetary gain or reputation gain/loss etc…).

So, “don’t bring me problems, bring me solutions”…

1)      Familiarise yourself with the Project Management triangle – learn how to sell it

2)      Stress what can actually be achieved given the available resource/timescales – focus on the positive!

3)      Offer options e.g.

  1. for $xUSD we could reduce timescales to two months
  2. by reducing the complexity/scope of feature Y we could deliver in two months.

4)      Consult the business case – can you actually afford to deliver the proposition ‘safely’ by e.g. expanding the delivery team?

5)      Review the scope and determine what drives the ROI – you will often find that a small fraction of the scope drives the bulk of the value.

6)      Conduct a risk assessment e.g. what would happen if you were to fail – would the impact be less or more desirable than an up front increase in cost? How could you mitigate/eliminate these risks?

The key to successful project delivery is to manage expectations, prioritise initiatives and agree a delivery strategy based on realistic set of assumptions.

Collate the facts and present only these facts and options. You can argue with opinion but facts speak for themselves.

A Product Owner or anyone managing a P&L will be ultimately looking to deliver value – this might be in the form of market share, revenue, reputation etc.  They will be looking for the ‘best deal’… it’s your responsibility to help them find the ‘best deal’.

So, keep it real and take time out to ensure you can back up all of your assumptions.  If you don’t, you will no doubt end up with egg on your face.

Using ‘Spikes’ in Agile Software Development

Posted by Tara Hamilton-Whitaker on September 29, 2009

‘Spikes’ are time boxed periods of research and development used in Agile Software Development environments to research a concept and/or create a simple prototype.

Spikes will usually take place in between sprints and are often introduced before the delivery of large Epics or User Stories in order to:

  • Secure budget
  • Expand knowledge
  • Proof of concept

The duration and objective(s) of a Spike will be agreed between the Product Owner, Product Manager and Delivery Team before the start.  They will normally be shorter than a standard sprint, however can range in duration from a few hours to a few days long or more. 

It is important to keep focused and during a Spike – ultimately, we want to get back to delivering tangible value as soon as possible!

Unlike Sprint commitments, Spikes may or may not deliver tangible, shippable, valuable functionality.  For example, the objective of a Spike might be to successfully reach a decision on a course of action.

With that said, a prototype created during a Spike may sometimes evolve into the final product or may be used verbatim in a future release.

For larger teams, a Spike might be accepted as one of many sprint delivery objectives

You might choose to do this in any or all of the following circumstances:

  • A multi-team environment with synchronised sprints
  • Only a few members of a sprint team can/should focus on delivering the Spike

One may ask how you reflect the delivery of a time boxed piece of effort alongside user stories on a burndown chart.

You have two options:

  • Do not include the spike in your burndown chart
  • Burn down in hours

If you traditionally burn down in story points, you should probably omit the Spike from your burn down.

You should still discuss the findings at the Sprint Review and the success of the sprint will still depend on the successful delivery of the pre-agreed Spike objective alongside other Sprint objectives.

If you burn down in hours, then burn down on time elapsed as opposed to the perceived number of hours required to deliver the objective.

Remember, Spikes are time boxed – the Spike is over when the time is up, not necessarily when the objective has been delivered.
