Focus On What To Leave Out

As an avid photographer I’ve learned a lesson that sometimes a well composed photo depends more on what is left out of the photo. More is not always better and can sometimes ruin what could have been a good composition. As an example, this photo is as was taken. I realized there were distracting elements (the house, dead tree) and the composition was just not one that created a compelling photo. The highlighted section is where the final crop was made. I left out more than I left in and I believe the end result was a more pleasing composition. You can see the final image here but that is not relevant to this article. I believe this concept can be applied to software development. We talk about determining the minimal marketable features, those that must exist for a product to meet the user’s needs. This requires us to be very intentional about what we leave out. The Standish Group notes that 45% of software features are never used and only 20% are always or often used. Those are astounding figures that illustrates the tremendous potential for wasted effort and time in a software development project. We must become better a composing a frame that contains only those features required to satisfy our customers and leave everything else out of the frame. These unused features come from many sources: product owners, customers, and even the software development team. We get caught in the trap that we need to capture everything, provide all possible features, or convince ourselves that while we are working in some part of the code there is little cost in adding just a few more capabilities. As well meaning as we believe we are, these non-necessary features exacts a ongoing cost. Costs from unused features that must continue to be tested, increased difficulties for adding new features, and increased technical debt. Recently I worked with a client that was debating on whether or not to add a capability to allow multiple items to be selected and then updated with the same information or just provide the capability one item at a time. From the customer’s perspective the real requirement was to be able to select an item and update. Doing so for multiple items would be a nice to have but _not_ necessary. After much debate the product owner made the the decision to not add the multiple select capability. It was not a minimal marketable feature and should be left out. It was a beautiful thing. Always be mindful of what is necessary and be very aware of the true cost of adding capabilities that appear simple to deliver but do not contribute to the final composition. Be ruthless in cropping out unnecessary elements and focus on those items that create a great composition.

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
GLASS'S INFORMATION SERVICES

“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
SUNCORP

“I worked with Kelly on many projects at IPC and I was always impressed with his approach to all of them, always ensuring the most commercially viable route was taken. He is great at managing relationships and it was always a pleasure working with him.”

BEATRIZ MONTOYA/CONSUMER MARKETING DIRECTOR
IPC MEDIA

“I worked with Kelly whilst at Thoughtworks and found him to be a most inspiring individual, his common-sense approach coupled with a deep understanding of Agile and business makes him an invaluable asset to any organisation. I can't recommend Kelly enough.”

PETER THATCHER, SENIOR ACCOUNT DIRECTOR
ThoughtWorks

“Kelly was a brilliant CTO and a great support to me in the time we worked together. I owe Kelly a great deal in terms of direction and how to get things done under sometimes difficult circumstances. Thanks Kelly.”
