Benefits of Agile Adoption – from a manager

Posted on by

To help some peers advocate for agile adoption, I prepared an experience report to demonstrate how my old team benefited from XP and Scrum practices. This is an extension and refinement of an earlier post on the benefits of XP.

Team Cohesion

yellow rope with knot by limonada on flickrBefore and during our agile adoption, I informally administered the Gallup Q12 employee engagement survey. It is composed of twelve simple questions. Agreement correlates to retention, customer loyalty, safety records, productivity, and profitability.

From the beginning to the mid-point of our adoption, staff went from a response rate of 70% agreement 30% disagreement to 80% agreement, 15% neutral and 4% disagreement.

The most improvement was in daily opportunities “to do my best” and daily feedback on performance and expectations.

I’m convinced if I had administered the Q12 late in our adoption, we would have had even better results. The key un-addressed concerns were about having a best friend at work and feeling connected to the mission of the company. By 2007 our team grew to include people brought in by personal recommendation of other members of the team and our portfolio included consumer facing work directly for our CEO.

Rather than re-take the Q12, we undertook a 360° performance review. That we did this on our own initiative shows just how much trust we had built with each other.

Test Coverage/Code Quality

Green Light by wiccked on flickrXP practices enforced methodical unit test coverage, mutually arrived at coding conventions, and real-time code inspection by multiple members of the team. The team went from no unit test practice to comprehensive coverage over the business logic and controller layers. (Unit tests against data access and gui were less comprehensive. I don’t intend to get in the middle of that debate here.)

A user story, test-driven approach to development has been shown to reduce defects in final testing by 40%.

XP and Scrum force conversations between the development team and product owner that incentivize all to build quality into the software rather than allowing technical debt to accumulate and relying on downstream QA process to fix the application.

In 2006-2007 there were no business impacting failures of our internally authored software. We were able to function as a project team with no dedicated developer maintenance staff. Change requests were minimal enough that we were able to prioritize them into our project sprints as overhead.

Reduced Risk

While any team has experts, “Agile” practices reduced our reliance on “specialists”. The entire team was capable of working on and maintaining any aspect of the code base. We passed the “bus test”; despite our small size, no project was at risk if any given member of the team became unavailable.

Leadership

Our team raised our skills and began contributing to our field. We write, present and teach at conferences on topics of scrum, XP and platform as well as contributing to open source projects and developer knowledge bases.

Recruiting and Retention

After establishing “Agile” practices we recruited skilled candidates from higher paying positions who desired to work in our culture and with our practices. We received inquiries from as far away as South America and Europe. Despite the reputation of our team and market demand we retained staff.

An additional benefit is that pairing provided an efficient on-boarding process for new hires. Developers joining the team provided immediate contribution. A metrics-based way to demonstrate this is to show that sprint commitments weren’t affected new hires first weeks. I observed that but mainly base this on comments from the team lead and existing members of the team.

Workplace Diversity

A 2006 paper by McDowell, Werner, Bullock and Fernald found that pair programming practice, “may help increase female representation in the field.”

Agile values and practices support a collaborative, empowering and sustainable work place. Such environments support diversity and take advantage of the breadth of experience each worker represents.

Client Satisfaction

We asked for quotes from our clients, vendors and even competitors which we included in our budget presentations (I’ve pretty aggressively scrubbed them):

“Working with the agile Software Development team has been rewarding on many levels…it’s a team that celebrates creativity, organization, listening, feedback, openness, honesty…and is proof positive that a great process results in great product. I look forward to our very regular meetings (I even readjust my travel schedule as much as possible to not miss anything) and am never disappointed. They are an engaging and engaged group of individuals.” – CEO

“[____ saved] half a head in [another team] and a full head in my team.” – VP

“The _______ written by our development team are the guiding-light to our decisions. [third party solution] has a vast wealth of information but no good reporting and our in-house [solution] enables us to divine meaning from the mountain of data.” – VP Traffic Operations

“We also use [third party solution] for all of our broadcast networks but I have heard about your software technology for ____. We currently do that through manual operators but I’d like to understand how you do that more sometime and how it works…” – Senior Executive, Competitor

“Given the complexities of ____ that includes the combined limitations of automation, graphic and traffic systems I believe [the team] has created a solution that has proven to be much more capable than most systems than I’ve worked with.” – Vendor

Frequent Delivery, Adaptability

Throughout 2006-2007 our team of 3-8 developers balanced two simultaneous lines of work on diverse projects built in Microsoft Windows Forms, ASP.NET to SQL Data Analysis Services Data Warehouses, Vista compatible Windows Presentation Foundation and XAML, open source .NET MVC frameworks and Ruby on Rails including a rich windows application built on beta Microsoft Technology.

The team completed eight IT and three consumer projects while doubling head count from 5 to 10 (+2 contractors). We initiated our consumer product initiative and achieved our first release of a rich windows application with a six month allocation of effectively 1.5 – 2.5 developers.

Invention/Innovation

Agile practices evolved from Lean management and associated knowledge creation theory. In this, it shares ancestry with Six Sigma.

Agile is based on empirical not plan-driven process control. It is closer to lean product development than lean industrial manufacturing.

Lean product development models sustained innovation as a process of knowledge creation and conversion within an organization that acquires and shares learning in an cycles within and across teams and up and down from leadership.

Agile fosters true joint work which is the only form of workplace collegiality that advances organizational change and innovation.

Our consumer product was recognized for its design and implementation by Microsoft’s platform and developer evangelist team as well as by the WPF team. It achieved high ratings in usability testing with end users (avg rating 8 of 10) and showed potential to deliver on its revenue targets.

Our History of Agile Adoption

Posted on by

Birth of an Unusual Planetary System Courtesy NASA/JPL-Caltech.My development team began adopting Extreme Programming (XP) in January 2004.

Before this, we were hit and miss. Success relied on individuals. We had few shared practices. Our goal in going “Agile” was to consistently perform across projects.

“Agile” declares a set of common values and supportive practices. It fosters collaboration with customers and shared ownership within project teams.

In time, the team became proficient in core XP practices:

Planning

  • User stories
  • Iterative development
  • Tracked velocity
  • Daily stand-up meetings
  • Regular retrospectives with continuous improvement

Designing

  • Simple system metaphor
  • Use of development spikes
  • Refactoring

Coding

  • Onsite customer
  • Pair programming with switching
  • Test driven development (TDD)
  • Continuous integration
  • Collective ownership
  • Sustainable pace

Testing

  • Extensive unit test coverage
  • Bugs are resolved within the iteration
  • Acceptance testing by the on-site customer

Within a year the team’s performance was more consistent and visible. We were measuring our velocity and predictably delivering on our 30 day iteration goals.

We discovered our project management practices had become a bottleneck. We were clearly hitting idle periods within and around projects because of a failure to efficiently describe and prioritize work.

We introduced Scrum as a management framework on top of XP. It provided practices for organizing and prioritizing work. It helped us define roles and responsibilities.

We clarified our expectations of internal clients and achieved more efficient interactions overall. We created mechanism for reporting progress and costs to senior management.

In Q1 06, the team’s practices were evaluated by an Agile Coach, Jason Lewis. Among his findings:

Oxygen Media’s Agile software development process overall rates above average and is better then the benchmark team. The benchmark did have considerably more Agile experience, but less time together as a team.

In the evaluation of practices, the team was overall: 1) well above average to outstanding in the adaptive learning practices, 2) Above average in Sprint practices and 3) Average in planning practices. High points for the team’s individual practices were the retrospective and use of the wall for iteration tracking. The one low point was the maturity of acceptance testing.

When comparing roles to the benchmark team, the benchmark team had a much better customer role but the team was stronger in the developer and facilitator roles. When comparing the team’s adoption of the practice’s versus the benchmark the team was generally more effective. Iteration tracking was one key area the benchmark team was better, however, the team was much stronger in the all the adaptive learning practices.

Scrum Release Burndown by kjudyAfter the audit, we pre-staged our iteration planning, reduced our iterations to 2 weeks and formally planned releases.

We added discipline to our acceptance testing. We described acceptance tests in a narrative script authored by and exercised by our product owner (proxies).

We never automated acceptance tests for rich windows applications or systems tied to large, volatile back end data stores. But by Q3 2007, the team was using automated acceptance tests on it’s web applications.

The most drastic improvement however was in the customer role. Scrum defines the responsibilities of the product owner. In our case, that role was divided into two individuals.

The product owner, is an empowered single authority for prioritizing business value at the feature level. They are usually are executive level and work in the business unit “funding” the work. They also have working knowledge of the system to be built. Product owners participate in planning and review, and are available for ad hoc questions within iterations.

The product owner proxy is a member of the development staff who acts as onsite proxy for the product owner. This person assists in authoring user stories and maintaining a product backlog, meets regularly with the product owner, and acts in their place to broker decisions within the development team during iterations.

By Q2 2007, the team had product owner proxies for both our IT and our consumer facing work. Product owners included the VP of Broadcast Operations, VP of Ad Sales Traffic, our CTO, and our CEO.

Sprint Burndown by kjudyThroughout 2006-2007 our team performed exceptionally well, balancing two simultaneous lines of work and maintenance in both .NET and Ruby on Rails with four to six developers. Our projects delivered on client satisfaction, originality and early monetary goals.

Team members raised their skills and began contributing to our field. They were writing, presenting and speaking at conferences on topics of scrum, XP and platform as well as contributing to open source projects and developer knowledge bases. We were drawing positive attention from our peer community and within our company.

Our consumer product, Ript™, was recognized for its elegance in design and implementation by members of Microsoft’s platform and developer evangelist team as well as by members of the WPF team. It also achieved high ratings in usability testing with end users (avg rating 8 of 10) and showed potential to deliver on its revenue targets.

At the end of 2007 our company was acquired by a much larger television company. Software we wrote for internal use is considered valuable enough by the acquirer that they are hoping to transition into their much larger operations.

The Beauty of Team

Posted on by

Our team just beta-released our first consumer product. Along the way, they accomplished something of more strategic value. They matured into a performing, self-directed team.

The Team Ript Page

A decent manager encourages software developers to do their best work while allowing them full personal lives. The heart of this effort is fostering strong teams. Individuals have bad days, make mistakes, lose momentum. A team watches each other’s backs, challenges each other, teaches each other. They build upon each other’s creativity.

The beauty part for a manager is — if you create the right conditions, start with the right people, trust them and hold them accountable — the team does the hard work of becoming. They deserve full credit for their achievements including the most ambitious achievement which is themselves.

That doesn’t mean it’s easy. Getting this consumer product to the general public has taken fifteen months. From our first study of agile principles to our current practice has taken the better part of four years of continuous improvement.

Trust, the Product Owner, and the Team

Posted on by

KnotWe are currently working on a consumer software product named Ript. I feel extremely lucky to be a part of this project as does every member of my team.

If there is a single reason for this sentiment it is the deep collaboration between our product owner and the development team.

The Manifesto for Agile Software Development asks us to value:

Customer collaboration over contract negotiation

Contract negotiation within a single organization arises in conditions of low trust. One or both parties feel they need to explicitly document expectations to protect themselves.

A low trust environment is Hobbes state of nature as practiced by the software industry. Promises are prized more than outcomes. Authority and responsibility don’t reside in the same person. Incentives are not linked to outcomes. Blame brings more consequences than failure. Success is virtually impossible. Agile practices if they can be adopted at all are simply a mechanism for failing fast which has the virtue of saving the company money and sending talented people off to hopefully more rewarding jobs at other organizations.

Rising above this coding purgatory is an organization with some mutuality of sentiment and interest. A capable development team exists and business owners are both empowered and accountable. Here the organization can aspire to partnership.

But not all collaboration is equal.

In What’s Worth Fighting for Out There?, Andy Hargreaves and Michael Fullan describe the concept of bounded collaboration:

Bounded collaboration rarely reaches deep down to the grounds, the principles or the ethics of practice. It can get stuck with the more comfortable business of advice giving, trick trading and material sharing of a more immediate, specific and technical nature. Such collaboration does not extend beyond particular units of work or subjects of study to the wider purpose and value of what is taught and how. It is collaboration, which focuses on the immediate, the short-term and the practical to the exclusion of longer term planning concern.

This concept is applicable to the software setting which, like learning, is fundamentally about knowledge creation and sharing.

Bounded collaboration exists in software when the developers do not invest themselves in the business outcome of a project. This can occur through no fault of their own if the plan is vague, not shared with them, or if their input is not invited or listened to. Some managers simply don’t consider it important that technical staff buy into the vision or features of the software they’re building.

In such situations, developers shut off part of their brains. (for those of us who love our craft, a more apt description is cauterize part of our brains)

“I’m not personally invested in the business plan or priorities but I will execute on them as you (product owner) define it. Since I have no authority or meaningful influence on the plan or priorities, as long as I produce reasonably error-free code I refuse to be judged by how the product fairs in the marketplace.”

Scrum allows for success on these terms by assigning responsibility for the business outcome to the product owner and technical execution to the team. If the product owner has a thoughtful strategy and deep insight into their customers a well-executed piece of software stands a chance.

But what price does an organization pay for bounded collaboration?

Knowledge Creating CompanyInnovation – A company that does not engage fully with its workers diminishes its ability to think deeply about a problem and to surprise itself with unexpected solutions. It therefore fails to be what Ikujiro Nonaka and Hirotaka Takeuchi describe as a Knowledge Creating Company that can sustain success through its own invention.

A television company building consumer software – that’s audacious!

Our product owner is our CEO, Gerry Laybourne. This initiative is her idea but she partnered with the development team to craft the concept and feature set for our first consumer product, Ript.

Gerry has allowed us to fall in love with the project by leading us while listening to us. She’s given us the gift of high expectations demanding that the product be original, useful, and fun. She’s treated us as peers despite the fact she holds much more authority than we do. She’s shared her excitement for the product while sharing credit for it. She’s championed her priorities while allowing us to question any and all aspects of the product. We’ve both had the pleasant experience of disagreeing and realizing the other was right.

Yes, the product owner is the single wringable neck – she’s championing an entirely new line of business at her company – but I’ve never seen a team fight so hard to get in the noose with her. That’s trust.

To quote Jeff Sutherland, “Great scrums require great product owners.”
