Analytics Requirements: Avoid a Y2.xK Crisis

Even though it happens annually, teams building new visualizations often forget to think about the effects of turning over from one year to another.

In today’s fast paced, Agile world, requirements for even the most critical dashboards and visualizations tend to evolve, and development often proceeds iteratively from a scratchpad sketch through successively more detailed versions to release of a “1.0” production version. Organized analytics teams evolve dashboards within a process framework that include checkpoints ensuring standards are met for security, reliability, usability, and so on.

A reporting team can build a revolutionary analytics capability enabling unprecedented visibility into operations, and then, if year turnover isn’t included in requirements, experience embarrassing errors and usability challenges in the January after initial deployment. In effect, the system experiences its own Y2.xK crisis, not too different from the expected Y2K crisis 16 years ago. Continue reading

Protect Your Culture: Screening for authoritarian project leaders

Bugs BunnyIt’s fashionable today to talk about the risks of authoritarianism in the political sphere. I’m not going to speculate on that, but such talk got me thinking about the same tendencies among IT project leaders. What is an authoritarian personality? (Yes, that’s actually a thing.) Is it truly antithetical to a healthy project? If so, how can you screen for it in hiring?

Recently, ArsTechnica ran an article that offers a survey of research on authoritarian personalities conducted since the 1940s. The bottom line for us is that those with authoritarian tendencies more often Continue reading

More on the Agile Architect: Process and Knowledge Transfer

webscrum_2444372bI’ve written about groupthink-related quality challenges on Agile projects, and the architect’s role in preventing groupthink from degrading quality. I’ve seen other risks related to the cohesion and potential insularity of successful Agile teams, and the architect is also well positioned to help prevent these: a tendency to neglect setting up and documenting repeatable processes, and a similar tendency not to share of knowledge and lessons learned outside the Agile team.

No More Enterprise Data Sinks – An Agile Data Warehousing Manifesto

SinkOver the past year I’ve reviewed what seem like countless plans for enterprise data warehouses. The plans address real problems in the organizations involved: the organization needs better data to recognize trends and react faster to opportunities and challenges; business measures and analyses are unavailable because data in source systems is inconsistent, incomplete, erroneous, or contains current values but no history; and so on.

The plans detail source system data and its integration into a central data hub. But the ones I’m referring to don’t tell how the data will be delivered, or portray a specific vision of how the data is to drive business value. Instead, their business case rests on what I’ll call the “railroad hypothesis”. No one could have predicted how the railroads enabled development of the West, so the improved data infrastructure will create order of magnitude improvements in ability to access, share, and utilize data, from which order of magnitude business benefits will follow.* All too often these plans just build bridges to nowhere.

Assumptions: A Key to Technical Leadership

DonkeyThere’s an unfortunate and rather rude saying about assumptions that I’ve found popular among IT folks I’ve worked with. I say unfortunate because, to me, assumptions that are recognized early and handled the right way are a key to successful projects. Technical players who use assumptions well can help set projects on the right path long before they go astray.

Sometimes on waterfall and hybrid projects technical players are asked to estimate work early, before requirements are complete. My instinctive reaction is not to provide an ungrounded estimate, but that’s not helpful. The way to handle this uncomfortable uncertainty is to fill out the unknowns with assumptions: detailed, realistic statements that provide grounding for your estimate. Continue reading

Get Business Requirements Right by Resolving Many-to-Manys

Logical data modeling is one of my tools of choice in business analysis and requirements definition. That’s not particularly unusual – the BABOK (Business Analysis Body of Knowledge) recognizes the Entity-Relationship Diagram (ERD) as a business analysis tool, and for many organizations it’s a non-optional part of requirements document templates.

In practice, however, data models in requirements packages often include many-to-many relationships. I’ve heard experienced data modelers advocate this practice, and it unfortunately seems consistent with the “just enough, just in time” approach associated with agile culture.

In my experience unresolved M:M relationships indicate equally unresolved business questions. The result: schedule delays and budget overruns as missed requirements are built back in to the design, or the familiar “that’s not what we wanted” reaction during User Acceptance Testing (UAT). Continue reading

Requirements Half-Life

ThreeMileIslandI had pondered writing a post called “Requirements Decay” about how requirements don’t last forever. In my research I found that such a post, complete with “my” words “requirements decay” and “requirements half-life”, had already been done comprehensively here. In a compact argument underpinned by half-life mathematics, the anonymous author proposes that a requirement isn’t likely to stand unchanged forever and explores the implications.

For me, requirements decay is an idea that helps us think realistically about project planning and improves our chances of meeting business needs. Continue reading

Jürgen Klinsmann’s Waterfall to Agile Transition

KlinsmannAndDonovan

How does this sound as advice for an app dev manager leading his or her team from waterfall to Agile?

  • Clearly articulate a compelling end-state vision
  • Work from a position of authority
  • Weather the storms
  • Reward creativity while fostering improvement

A post at scrumsource.com lists leadership, organizational culture, and people as three of the five key factors in making the transition. Another at the Scrum Alliance site describes the transition as a migration from externally-organized to self-organizing teams. In my experience the transition requires leadership by a strong advocate who shows the way to willing, empowered team members.

The US men’s national soccer team (USMNT) is playing out a strikingly similar transition. Continue reading

Followership IV: How to criticize your boss

ObamaAndMcChrystalThis is the latest entry in an occasional series on followership. The premise, as stated here, is that not everyone gets to be a leader, and most leaders are also followers in their own right. The project manager follows instructions from the project sponsor, the CEO from the board, the politicians from the polls, and so on. Whoever you are, you spend a lot more time following than leading. As Bob Dylan put it so well, “you gotta serve somebody.”

The good follower is not a “yes man“. In the professional world I inhabit those who move “up” the hierarchy tend to retire technical skills in favor of architecture, proposal writing, and management. The relationship of manager to employee becomes more like agent to actor or musician, where the supervised employee is the “talent”.

In these conditions the old concept of top-down decision making seems quaint. Important choices require information from all perspectives, and organizations shut out those with knowledge of the details at their peril. The best decision makers search out diverse ideas before choosing a direction. Continue reading

A Fist Full of Agile Critiques

Out of curiosity I recently reviewed articles critical of Agile Methodologies. I had expected agile-versus-waterfall arguments and attacks from vendors selling new alternatives, but even given the reputation that advocates have for flaming well-intentioned critics, I wasn’t prepared for the level of emotion I found.

My opening position was that Agile techniques are great, but like any other tool there are limits and prerequisites. The critical articles I read strengthened that view. Let’s review three examples that stood out, in reverse order: Continue reading
