Differences between Kanban and Scrum

Recently when attending the 5-day Agile 2014 conference in Orlando, Florida, I had an opportunity to discuss various agile implementations. Some of the discussions centered on selecting the right type of agile methodology to consider for software implementations from extremely regulated medical devices industry and government projects where Scrum was considered prevalent. Then, when I found in my network of work and friends, there were questions that revolved around using Kanban because Scrum wasn’t working.

Having used Kanban and Scrum, I wondered why there is still confusion among the early adopters of Agile and why Kanban would be considered as a substitute for Scrum. Unclear understanding of agile concepts may lead to failure just like how people created a non-existent theory of waterfall based on inaccurate practices (Rajagopalan, 2014). So, I focus below on a comparative study of the basic premises between Kanban and Scrum. I hope this article captures the essence of these approaches demystifying the confusion and helping in the selection of the right approach for the challenge at hand.

One of the primary differences is that Kanban is a method that can be used independently or along with other approaches like Scrum. This is why we even have derivative approaches like the Scrumban.

Concept	Kanban	Scrum
Management focus	Maximize resource usage avoiding delay and enhancing accountability to support flow.	Consistent delivery in the cadence of execution, as the features in the product backlog is delivered.
Operating rhythm	No time-boxed iterative development exists.	Time-boxed iterative development – usually two to four weeks.
Granularity of work	Focus is at the task level for which the scope of work is generally known.	Focus is at the user story level for which the scope may not always be known, requiring it to be estimated before tasks can be identified and taken up by the team.
Agile Estimation & Planning	Estimation is generally not done. There is little to no ambiguity on the task that any member of that team should be able to take on the next available task and execute it.	User stories are estimated. Then, they are prioritized, and risk adjusted so that these are included in the release and iteration planning.
Value Delivery	Every task completion may not necessarily add minimally marketable value to the customer. Task identification and dependency require careful coordination.	The cadence of release and iteration planning focuses on adding minimally marketable feature through the scrum cycle. The self-organized team determines the task identification and dependency.
Progress Tracking	Flow of items throughout the lifecycle limiting delay. This is why the focus is on limiting “Work in progress (WIP)” is promoted through “Don’t Repeat Yourself (DRY)” focuses on maximizing work not done	Focus is on tracking the velocity measuring the user stories done and delivered to customer in an iteration
Utility value	Better for managing workload and resource management. E.g.: How many projects of different combinations can be taken up by a project?	Better for managing products, programs, and projects.
Thoughts to consider in software development	Use of Kanban for software development may impede flow if all the units don’t consume the work produced at the same speed. Therefore, additional processes must be in place to support Kanban. E.g.: QA not having capacity to test code developed by engineering team. If QA’s capacity comes from the fact that more defects are found in the build, then, more granularity in tasks to ensure proper code review, unit testing, and documentation are processes that the organizations must have in place.	Implementing Scrum doesn’t mean the ability to write user stories and avoiding documentation completely! This requires a management shift to ensure critical thinking on the product, program, and projects. If iterative delivery is not understood by the management and client, then, Scrum is not an option to consider.

In summary, Kanban and Scrum are both light-weight approaches, but the operating philosophy is different. Scrum focuses on the work being delivered to customers through multiple iterative deliveries of minimally marketable value by assembling a cross-functional, skilled, and self-organizing team or team of teams. Kanban, on the other hand, is a pull-based system and focuses on the visualized workflow where flow is maximized by limiting what gets worked on by the team. Although both approaches require prioritization in the items represented in the backlog, Scrum team can’t pull an item outside of the Sprint backlog when they have capacity. Kanban team can pull the next priority item from the backlog. So, depending on what product, service, or result the team is delivering, or the benefit being sustained in operations, Scrum, Kanban or Scrumban may work. Select the right tool for the right job!

Essential Leadership behaviors for Agile Transformation

In the recent Scrum Coaches Retreat that I attended, I saw a pattern where the majority of the topics presented for discussion centered on organizational transformation and implementing agile correctly. The topics ranged from change management traits for individuals and organizations, executive leadership behaviors, coaching approaches for executive leadership, coaching for non-technology groups to implement agile, facilitation techniques for team trust, and scaling agile for coaching within an organization. Having established, led, and managed a program management office (PMO) in a healthcare IT and professional services industry and with a strong desire on leadership behaviors through project management and product development, I joined the team on this theme seeing an increasing focus around executive leadership behaviors for leading organizations to embrace agile successfully (“Build an Agile Organization Executive Coaching”, 2013).

Following the agile principles of user story development, our group with backgrounds from multiple industries began identifying the major categories of persona in today’s leadership that lacked understanding or came with a traditional mindset in transformation. These observations were later shared across the various participants from numerous countries during our daily retrospectives to further refine our persona categories. The major themes of persona classification of executives evolved are listed as follows that I have reordered in a continuous spectrum of the knowledge of agile in their implementation challenges.

Resistant: The executives that fall into this category are those that have a generational gap leading to a resistance in change. The relevance to current ways of managing projects or understanding product development is not in the radar screen for taking the organization to the next level. These leaders are more task-oriented managers than leaders who feel challenged that agile may not add value. “It has been working for me and so I see no need for agile” is the theme behind such leadership.

Never heard of agile: The executives that fall into this category are open to ideas but are unfamiliar with the agile framework.  This group’s lack of understanding may arise due to many reasons such as their own personality towards new learning, lack of initiative, and firm’s industry representation to understand new trends. These members often rely on the experience of others bringing in consultant experience or another senior member to implement the transformation. If the consultant or the senior members fail to apprise of the executives of the implementation challenges in product development, skills reorientation, and the structure required for agile development to thrive, then, these executives lose faith in Agile.

  

Big Vision: These groups of executives understand that their current structure is not in line with their big vision for growth. They recognize that they need to develop products differently for competitive position of themselves in the marketplace or excelling in doing things efficiently. They have heard of the agile framework through their own due diligence to implement their growth ideas and look forward to their delegates for support.

Misinformed: Similar to object oriented programming where the subclass inherit characteristics of super class, this group of executives have had bad experience from the earlier bad implementation in their organization or in a different organization. Their “bad taste” of agile implementation shouldn’t be attributed to agile framework’s failure but the failure of those leaders or consultants that didn’t implement a stable and scalable solution.

Metric Oriented: Some executives have an instinct to not just focus on the profit motive but also establish key performance indicators. But lack of having correct types of metrics and threshold to begin with may impede successful implementation.

Insufficient Experience: This final group leans on those consultants or senior members that are brought into the organization just because they have implemented agile in their previous job. As Boyatzis and McKee (2005) noted, these high-profile members need to understand the emotional makeup of the new organization and not just their own personal success in their previous job. The reliance on a structure or set of tools that they had found useful previously but failure to understand the new organizational structure, impediments, and product makeup among others add up to the challenge of insufficient experience that these roles bring to implement agile transformation successfully.

In the end, the successful implementation relies on proper coaching of the organizational executive for leadership behaviors that they need to inculcate to succeed leading to forming a team that can coach and train the organization. If the leadership has not bought into the fundamental twelve agile principles for successful agile transformation and middle management members like functional team leads and project management not trained on product ownership, project team leadership, process governance, and client management, then, the fragile leadership should be held accountable for agile framework’s failure.

Do you think there may be other persona besides these persona classifications?

Execution as a Strategy in Acquisition – Relevance to Agile Transformation

In one of the networking events on effective agile transformation that I facilitated, one of the learners asked a question about how agile did not measure well in an organization that the learner’s organization acquired. The learner reasoned that the acquired company was a smaller organization that claimed financial profit in a niche market but has been bleeding after acquisition when adopting agile. While the specifics of the details have to be left out in this blog, the discussion made me realize some of the pitfalls in agile adoption in mergers & acquisition prior to shifting responsibility of failure on agile practices.

This quest for executing mergers & acquisitions (M&A) successfully led me to pursue several articles and books which made me feel that “Execution” itself should be “strategically” thought through by leaders within an organization and particularly with M&A.  Paul Burmeister, who has executed in the capacity of COO and CFO in many industries, quotes multiple ideas to ensure that the M&A activity becomes successful, emphasizing critical importance of the leaders’ synergy from both the organizations to establish success factors to measure the efficiency of integration.

Among these stands out an important point on whether the M&A focuses on products, processes, and intellectual capital (Dahl, 2012). While M&A accelerates the acquiring organization’s competitive advantage by leveraging the new product line or the intellectual capital that leads to quicker access to additional markets horizontally or vertically, the reference to processes differentiated how clash of various processes (waterfall versus agile) may have to carefully weighed.

I think here is where organizational leaders may be failing to adopt asking “what would have to be true for the” execution to continue to be a fantastic choice? (Lafley & Martin, 2013, p. 204) If leaders failed to understand the twelve principles behind agile and scale them appropriately, then, they have created an organizational impediment for agile to fail their organizational success. Rationalizing on how the acquired company has always functioned differently and seeing no need to change fails to take advantage of the additional capabilities that come with the acquisition, reasons Jeff Sutherland, one of the contributors to the Agile Manifesto, who attributed the organization’s failure to remove impediments for Agile to fail (Larman & Vodde, 2011).

Once we come to terms that we have to review the processes in place, there are a couple of additional areas to look at for successful integration of agile in M&A. These include identification of proper product owners and tools for interaction. Unleashing properly spaced-out adoption of skilled people to work as product owners that understand the agile principles of establishing a good risk adjusted product and sprint backlog, prioritizing the backlog to build trust and maintaining a cadence balancing team’s commitment in distributed and virtual teams that have to be embraced, and recalibrating on the tools of communication is vital. Charlie Rudd, CEO of SolutionsIQ, underscores how organizations fail to implement agile without building the product owner capability (2013, para 5). Firms should give importance to training in such a way that time is made for people to get trained, says Larman & Vodde (2011, para 4).            

Given these observations, what other execution specific strategies should one consider for agile to succeed with M&A activities? Should there be a standardized M&A integration checklist put together for agile success and if so, what are some pointers to definitely consider? Please share your thoughts.
