Agile and geographical distribution

This content is syndicated from [email protected]: Strategies for Scaling Agile Software Development by ScottAmbler. To view the original post in full, click here.

One of the scaling factors called out in the Agile Scaling Model (ASM) is "geographic distribution".   As with the other scaling factors the level of geographic distribution is a range, with co-located teams at one extreme and far-located at the other.  When your team is co-located the developers and the primary stakeholders are all situated in the same work room.  If you have some team members in cubicles or in separate offices then you're slightly distributed, if you're working on different floors in the same building you're a bit more distributed, if you're working in different buildings within the same geographic area (perhaps your team is spread across different office buildings in the same city or some people work from home some days) then your team is more distributed, if people are working in different cities in the same country you're more distributed, and finally if people are working in different cities around the globe you're even more distributed (I call this far located).

As your team becomes more distributed your project risk increases for several reasons:
  1. Communication challenges.  The most effective means of communication between two people is face-to-face around a shared sketching space such as a whiteboard, and that requires you to be in the same room together.  As you become more distributed you begin to rely on less effective communication strategies.
  2. Temporal challenges.  When people are in different time zones it becomes harder to find common working times, increasing the communication challenges.  One potential benefit, however, is the opportunity to do "follow-the-sun" development where a team does some work during their workday, hands off the work to another team in a significantly different time zone, who picks up the work and continues with it.  This strategy of course requires a high degree of sophistication and discipline on the part of everyone involved, but offers the potential to reduce overall calendar time.
  3. Cultural challenges.  As the team becomes more distributed the cultural challenges between sites typically increases.  Different cultures have different work ethics, treat intellectual property differently, have different ideas about commitment, have different holidays, different approaches to things, and so on.
As you would imagine, because the project risk increases the more distributed your team is, the lower the average success rates of agile projects decrease as they become more distributed.  The 2008 IT Project Success Survey found that co-located agile teams has an average success rate of 79%, that near located teams (members were in same geographic area) had a success rate of 73%, and that far-located agile teams had a success rate of 55%.  The success rate decreases similarly for project teams following other paradigms.

The practices that you adopt, and the way that you tailor the agile practices which you follow, will vary based on the level of geographic distribution of your team.  For example, a co-located team will likely do initial architecture envisioning on a whiteboard and keep it at a fairly high-level.  A far-located team will hopefully choose to fly in key team members at the beginning of the project, at least the architecture owners on the various sub-teams, to do the architecture envisioning together.  They will likely go into greater detail because they will want to identify, to the best of their ability, the interfaces of the various subsystems or components which they'll be building.  They'll also likely use a modeling tool such as Rational Rhapsody to capture this information (note that it is very possible to use CASE tools in an agile manner, and that some agile teams in fact do so as the 2008 Modeling and Documentation Survey shows).

Geographically distributed agile teams, at least the effective ones, will also use tools which reflect the realities of agile geographically distributed development (GDD).  The Jazz platform tools, particularly Rational Team Concert (RTC), are developed with agile GDD in mind.  In fact, the RTC team itself is an agile GDD and they use RTC to develop RTC.  Although index cards are a great way for co-located agile teams to capture high-level requirements such as user stories, you need an electronic strategy for a GDD team.  RTC also supports communication between team members, distributed debugging, and many other features which distributed teams will find useful.

Interestingly, the Agility at Scale 2009 survey found that it was quite common for agile teams to be geographically distributed in some manner:
  • 45% of respondents indicated that some of their agile teams were co-located
  • 60% of respondents indicated that some of their agile teams had team members spread out through the same building
  • 30% of respondents indicated that some of their agile teams were working from home
  • 21% of respondents indicated that some of their agile teams had people working in different offices in the same city
  • 47% of respondents indicated that some of their agile teams had team members that were far located
The bottom line is that some organizations, including IBM, have been very successful applying agile techniques on geographically distributed teams. In fact, agile GDD is far more common than mainstream agile discussion seem to let on.

What People Say

“Kelly revolutionised the way our digital department operated. A true advocate of agile principles, he quickly improved internal communication within our teams and our internal clients by aligning our business and creating a much enhanced sense of transparency in the decisions the business was making. Kelly also introduced a higher sense of empowerment to the development teams...”

PETER SILVA-JANKOWSKI
IPC MEDIA

“Kelly’s a leading program director with the ability to take charge from day one and keep strong momentum at both a program and project level driving prioritisation, resourcing and budgeting agendas. Kelly operates with an easy-going style and possesses a strong facilitation skill set. From my 5 months experience working with Kelly, I would recommend Kelly to program manage large scale, complex, cross company change programs both from a business and IT perspective.”

LUKE SHARKEY /STRATEGY & IMPLEMENTATION LEADER
SUNCORP

“Kelly is an extremely talented and visionary leader. As such he manages to inspire all around him to achieve their best. He is passionate about agile and has a wealth of experience to bring to bear in this area. If you're 'lucky' he might even tell you all about his agile blog. Above all this, Kelly is great fun to work with. He is always relaxed and never gets stressed - and trust me, he had plenty of opportunity here! If you get the chance to work with Kelly, don't pass it up.”

GILES BENTLEY, DEVELOPMENT & OPERATIONS DIRECTOR
TIME INC

“Kelly is an Agile heavy-weight. He came in to assess my multi-million $ Agile development program which wasn’t delivering the right throughput. He interviewed most of the team and made some key recommendations that, when implemented, showed immediate results. I couldn’t ask for more than that except he’s a really nice guy as well.”

DAN PULHAM, DIGITAL DIRECTOR
TELSTRA

“Kelly and I worked together on a very large project trying to secure a new Insurer client. Kelly had fantastic commercial awareness as well as his technical expertise. Without him I would never had secured this client so I owe a lot to him. He is also a really great guy!”

GINA MILLARD
GLASS'S INFORMATION SERVICES

“Kelly came to the department and has really made a huge impact on how the department communicates, collaborates and generally gets things done. We were already developing in an agile way, but Kelly has brought us even more into alignment with agile and scrum best practices, being eager to share information and willing to work with us to change our processes rather than dictate how things must be done. He is highly knowledgable about agile development (as his active blog proves) but his blog won't show what a friendly and knowledgeable guy he is. I highly recommend Kelly to anyone looking for a CTO or a seminar on agile/scrum practices - you won't be disappointed!”

ANDY JEFFRIES/TECHNICAL LEAD
IPC MEDIA

“Kelly was a great colleague to work with - highly competent, trustworthy and generally a nice bloke.”

HANNAH JOYCE

“Kelly was engaged as a Program Director on a complex business and technology transformation program for Suncorp Commercial Insurance. Kelly drew on his key capabilities and depth of experience to bring together disparate parties in a harmonised way, ensuring the initiate and concept phases of the program were understood and well formulated. Excellent outcome in a very short time frame. ”

BRUCE WEIR/EGM
