1. 12 Factor Pipeline & Self Service Infra

Key highlights from

Juni Mukherjee and Nicola Paez

The concept of continuous everything

New Definition of DevOps PipelinePipeline was spanning every step from first check-in to go-live. As per the new definition is now encompassing a broader span of concept to cash.

Highlighted Few of the 12 Factors

• One codebase, many deploys• Strictly separate build, release and run stages• Store config in the environment/backing services as attached

resources

Concurrency & Disposability• Concurrency: Producer is aware of all consumers.

Consumer driven contract. Producers will create multiple instances to meet the consumer demand. End-to-end testing required for both consumer and producer together.

• Disposability: Producer is not aware of all consumers. Producer driven contract. You can kill producers without impacting consumers. End to end testing required only for consumer.

Selling/Distributing Distributed AppsJenkins X provides CI/CD for distributed applications orchestrated by Kubernetes. They can be packaged by Helm and sold using cryptocurrency on

Harbor.

2. Agile Quantified• Key highlights from Larry Maccherone

session. All data, analyses, and conclusions credited to Larry Maccherone and his collaborators in CMU Software Engineering Institute, and Rally Software.

• Rally Data: 10,000 teams for most of the findings, 1,500 teams where needed survey response (e.g. tester:dev ratio).

• Time period was roughly 2011 to 2014, data anonymized for analyses.

Statistical rigorous work - so pay attention!

Apply in Context

Team Size• 7 +/-2 is still the

most optimal• But, if you are doing

well with larger teams, with fewer inter-team dependencies, 9-15 size works well too

Iteration Lengh

• Longer iterations correlate with higher quality• Shorter iterations with higher productivity & responsiveness• Teams using 2-week iterations have the best balanced performance

Ratio of Testers to Developers

• More testers lead to better quality• But they also generally lead to worse productivity and responsiveness• The teams that self identify as having no testers have: the best productivity, almost as good

quality, but much wider variation in qualityCredit: Larry Maccherone while at Rally Software and Carnegie Mellon University

Estimation Process

• Full Scrum (79%) = Story Points + Task Hours

• Lightweight Scrum (10%) = only Story Points

• Lightweight Scrum performs better overall

• Teams doing full Scrum estimation have 250% better quality than teams doing no estimates

Co-located vs. Distributed Teams

Teams distributed within the same time zone have up to 25% better productivity

Stable & Dedicated Team Mix

• Stable teams result in up to 60% better productivity, 40% better predictability

• One out of four team members changes every three months!Credit: Larry Maccherone while at Rally Software and Carnegie Mellon University

3. Monoliths vs. MicroservicesKey highlights from Ryan Bergman

Monoliths communicate 45x faster & make it easy to:

• Move code & change dependencies

• Find dependent code• Track & monitor• Add new features

Microservices scale by adding instances & make it easy to:

• Keep things apart & not become a ball of mud

• Deploy changes for just one thing

• Deal with technical debt

Prerequisites for Microservice• DevOps culture, automated deployment is mandatory. You

can’t do it from AWS console.• Refactor the monolith. Instead of grouping the code by

framework use domain driven design concepts to group the code related by domain or features.

• Use tools like Structure 101 Studio for Java to view and fix programmatic complexity.

• Refactored code can be isolated by private scope. Use linters and package enforcers.

4. Probabilistic Estimation• Adam Yuret & Troy Magennis sessions on estimation• While there is value in the estimation process, and the

conversation that happens in that exercise, the estimate itself is not very useful

• Instead use statistical estimation, using real, recent data inputs– This spreadsheet helps forecast how long a single feature or

single project will take to deliver using agile (scrum or kanban) using Monte Carlo simulation

– http://focusedobjective.com/forecast_agile_project_spreadsheet/

Keyboard Time vs. Elapsed TimeWhen offering their estimate, developers don’t account for wait time and dependencies on others

From Troy Magennis’ Keynote

Simple Spreadsheet

• Inputs about your project at hand

• Recent data for your team - from your ALM system

• Spreadsheet does rest of the work - using Monte Carlo simulation, using Weibull distribution curve

From the paper by Troy Magennis

Diminishing Information Value

Net-Net

5. Innovation AccountingKey highlights from Joe Vallone

• Data indicating pivot is ignored - HIPPO/Squeaky Wheel/FIFO.• Sunk costs must be ignored. Money allocated isn’t money

spent.• Weighted Shortest Job First as a way to prioritize projects for

funding WSJF = Cost or Delay/ Job Size.• Cost of delay = User-Business Value+Time Criticality+Risk

reduction or opportunity enablement value.

Modern Innovation Process

Prerequisites for business agility are 1) Predictability 2) Fast feedback to gather data and learn 3) Ability/ willingness to pivot or persevere 4) Lean-agile budgeting

NPV/IRR old methods-insufficient to measure risk in complex projects

Leading vs. Lagging IndicatorsROI, revenue, etc., can’t be used to prioritize projects as they are lagging indicators. The bad news is that there are no standard lagging indicators. “One metric that matters” changes from time to time. You might get attracted by a vanity metric if you don’t think.

6. Value Over Cost

• From Business Value Estimation session by Chris Sims

• Most teams spend way more time in cost/effort estimation of stories (seeking false precision), and not enough time on the business value estimate of each story

Value Estimation w/ Stakeholders• One simple technique is to have value estimation sessions, just

like planning poker sessions– Participants include all key stakeholders, facilitated by Product Owner– First force rank all stories on business value– Then assign Fibonacci (value) point cards to each story– PO benefits from listening to all the discussion/debate that happens

• Conduct planning poker and value estimation exercise independently, to not let one bias the other

• Then, do final prioritization based on both considerations– High value/low cost - quick wins, do them first– High value/high cost - try to break those stories down

Example

Why Focus on High Value Stories

From Jeff Sutherland’s Scrum@Scale Session

Need More Customer Validation

7. More than Lean Startup

Key highlights from Jurgen Appelo

He has added conceptualisation step to design thinking and lean startup

Hiring for Startup - A New Way• Hiring for startup is tougher than raising capital.• No office, hire globally, diversity is guaranteed.• No standup. Daily cafe, starts with 5 mins chit chat, topics

decided based on lean coffee style.It’s recorded on video.• Periodically the team meets at an exotic location. Money

saved on office is spent on these off sites.• Step-by-step process for the hiring funnel to weed out

unsuitable candidates as early as possible.

Crowdfunding Advantages• Hundreds of people who

invested in the venture became active advocates of the product.

• Going the VC route is unagile. Once you sign up, it’s hard to change directions. You can’t wait until the last opportune moment.

• Crowdfunding platforms charge 5 to 10%.

Golden Nuggets by Jurgen Appello• Most startups fail because they start scaling without validating.• Take time to stabilize after validation.• Startup = ideating + concepting + starting + validating + stabilizing.• Scaleup = scaling + establishing + expanding + maturing + exiting.• Lean canvas doesn’t connect the boxes correctly. The overlap

between various boxes can be better depicted by a model that resembles sequence diagram or a Gantt chart.

• Sequence diagrams can also be used to depict all the value streams and the current stage in their lifecycle.

Lean Canvas

Restructured Lean Canvas

8. Scrum@Scale• While SAFe is alive and well, Jeff Sutherland

(co-creator of Scrum) has offered a much simpler and lighter weight scaling framework Scrum@Scale

• SAFe gets some flak for being too heavy and bureaucratic - “just waterfall w/ Agile friendly terminology”

• Scrum@Scale LLC is a 50-50 JV w/ Scrum Alliance and Scrum Inc, offering trainings and certifications

Recent Issues - 2018

May-June 2018 Issue

S@S Promises Linear Scalibility

Scrum@Scale Framework

www.scrumatscale.com

S@S: Minimum Viable Bureaucracy• Three Scrum Teams

– Executive Action Team - removes roadblock above team level

– Enterprise MetaScrum - POs for refinement and prioritization

– Scrum of Scrums

• Strong Product Owner role reduces decision latency, which drives process efficiency

9. Learning to Experiment

Key highlights from Christopher Lucian, Jenny Wanger and Ian Maple

Design for Delight @ Intuit• Deep empathy - visit, observe,

take notes/photos, discover• Be a dummy, ask clarifications,

actively listen, don’t suggest• Go broad - generate many ideas• 2X2 narrowing - create grids

with word pairs speed/accuracy, cost/innovative, simple/versatile then put your ideas in the grid

A/B Testing• Good experimentation with quick feedback start narrowing the

choices. Time for A/B testing when the choice is narrowed to 2.• Take pride in measuring correctly, not in being correct.• Test something that is likely to change users’ behaviour.• External variables are likely to impact the results. But there is

no need to re-test if these are equally impacting A/B cohorts.

A/B Testing, continued...• Some bugs are likely to impact the test results. But check if the

bug is evenly impacting both A and B cohorts, then there is no need to fix and re-test.

• Data can be imprecise, pertaining to different time intervals, double counted etc. Accuracy costs; and is important. Double check your data if results are surprisingly favourable.

• Decide what is “good enough” to favour A or B before starting the experiment. Objective is to reach a decision.

10. Myth of 10x Developer• Paying for Performance...session by Adam

Yuret• Red Bead Experiment -

https://deming.org/explore/red-bead-experiment

• Variations exist in the system• All workers perform within a system that is

beyond their control• Individual performance rewards and

penalties don’t work

Just Regression to the Mean!

Myth of 10x Developer

11. Chaos Engineering

Chaos Monkey vs. Simian Army

According to Shahzad Zafar, Chaos Monkey only introduces random failures whereas the Simian Army does a lot more

• Chaos - Kills random instances• Chaos Gorilla - Kills zones• Chaos Kong - Kills regions• Latency - Degrades networks and injects faults• Conformity - Looks for outliers• Circus - Kills and launches instances to maintain zone balance• Doctor - fixes unhealthy resources• Janitor, Howler and Security do what their names indicate

What is Chaos Engineering?

It’s like setting up a scientific experiment:• Have a hypothesis - start with a why and expected behaviour• Have real-world events based on frequent incidents• Continuous experimentation - automate orchestration and

analysis of experiments• Measure business metrics & outcomes that will be impacted• Limit your blast radius• Make it as real as possible - ideally in production

Chaos Engineering - Recommendations• Start by testing the weakest link• Don’t forget to test people - identify your Brent• Inform stakeholders about risk of running experiments• Use value stream mapping to identify weak spots• Expect the unexpected, e.g., power outage results• Too many tools with dependencies - 1 out of 2 chance of

success.

12. Metrics for Agile

• Outcome vs. Output focus - Outcome Metrics Lead To Valuable Practices session by Skylar Watson, Tim Ottinger

• Goal-Question-Metric (GQM) Approach to Agile Metrics by John Tanner - https://www.leadingagile.com/2017/05/agile-metrics-gqm-approach/

• Outcome-Decision-Insight-Measure (ODIM) by Larry Maccherone - https://medium.com/@lmaccherone/odim-12d80823222

Balanced Metrics, Trending Pattern

Credit: Larry Maccherone, Troy Magennis http://focusedobjective.com/team-metrics-right/

For metrics to be useful, in identifying improvement opportunities

• Select a set of balanced & competing metrics

• Look at trend rather than static snapshots

• Measure at least one metric TREND in four different areas

Balanced Metrics For Teams (not from Agile2018)

1. Cycle Time for productivity, measure this from when work starts to when the feature is done. The shorter the cycle time, the more things are getting done in a given timebox.

2. Escaped Defects for customer satisfaction, measure this by the number of problems (bugs, defects, etc.) found in the product once it has been delivered to the user. The lower the defect rate, the more satisfied the customer is likely to be with the product.

3. Planned-to-Done Ratio for predictability, measuring is a simple exercise of documenting how much work the team commits to doing at the start of the sprint versus how much they have completed at the end of the sprint.

4. Happiness for team "health", build this into your sprint retrospectives. It creates awareness that puts the other three metrics into better context. If all the other metrics are perfect and happiness is low, then the team is probably getting burned out, fast.

Dominic PriceHead of R&D and Work Futurist at Atlasssian

The Future of Work and Healthy Teams• Efficiency vs Effectiveness

– Process vs Plays and Guardrails– Predictable vs Freedom– Outputs vs Outcomes

• Factories vs Labs– Status quo vs Use data and test assumptions– Fear culture vs Embrace failure

• Take Action!– Unlearn. Make work = play– Environment. Borderless. Curiosity > Consistency– Levers

Keynote Roundup

Keynote RoundupTroy MagennisFounder, Focused Objective; Former Sabre, Travelocity Executive

What is the story with Agile Data?• Data is not enough, charts are not enough• The story in the data must be told (& discussed) in

order to be convincing– Use historical data alone and we might be wrong due to context– Use intuition alone and we might be wrong due to cognitive bias– Data + Conversation

• Fastest way to get crappy data is to embarrass people• Better data come from safe, happy people• Measure outcomes not outputs

Kim ScottAuthor, Radical Candor; Former Google, Apple Executive

Keynote Roundup

Radical Candor: Love your work & the people you work with• Give a damn• Give Feedback

– Immediately– Criticize the situation, behavior and impact– Don’t criticize the personality– Criticize in private, praise in public

• “Clean Escalation”– Don’t let people talk badly about each other to you– Insist they talk with each other directly
