Lean Teams - Doing More with Less

•

1 j'aime•1,225 vues

Having a large consulting contract with money to burn can make it easy to succeed but what do you do when you’ve got a small team with limited resources? Taking inspiration from lean software development and lean start-ups I have singled out several principles that help agile teams get more out of less. Examples include Continuous deployment, FDD (Feedback Driven Development), and Kanban. I will explore what each of these are, how I applied them in the Rails stack and reflect on what effect they had on my team’s productivity and application quality.

...but

• need to pay the bills (still consulting)
• want to make progress with little effort
• so I started to learn about the strange, new
world

Guiding Principles

1. Focus on Value
2. Minimize Effort
3. Deliver Fast

1. Focus on Value

“First, learn what is core to what
you are building then provide just
that”

Add Nothing but Value

what is value? understand it
should be owned by everyone

Feedback Driven Development

• creating useful software that people value
• learning what reaches users
• process for validating change
• doing so with as little effort

Customer
Development

• reducing market risk
• what problem are you solving?
• who are your customers?
• will they pay for it?

Pivot

• tweak features to get better results
• if pivoting doesn’t work, remove

Simplicity

• strip features to the essence that achieves
value
• spiking large features
• “Do the simplest thing that could possibly
work”

Delay Commitment

• pushing off decisions, commitment until the
last possible moment
• yagni - you ain’t going to need it

Minimum Viable
Product
• Rails Rumble/Startup Weekend
• starting place for validated learning with the
least effort
• should be embarrassing
• early adopters see the potential

Kanban

• a pull-based system for continuous ﬂow of work
• project management tool
• expression of just in time
• emphasis on ﬂow

Kanban Beneﬁts
• simple, less process
• limit work in progress, maximize
throughput
• easy to change direction
• less inventory of requirements/stories
• less time in meetings
• more easily spot bottlenecks

Continuous Deployment

• automated deployment of completed code
to production
• ship features when ready

Details
• automated testing with continuous
integration
• simple deployment/rollback script
• ‘stop the line’ on failures
• real time alerts in production
• ﬁve whys - root cause analysis

Beneﬁts

• deliver features/bugs ﬁxes faster
• reduce shelf time for ﬁnished work
• eliminate waste in deployment process
• ﬁnd integration issues quicker and in
isolation

Takeaway

• don’t waste resources on stuff that doesn’t
matter
• pivot as you learn from your users
• focus on ﬂow
• ship when features are ready

Microsoft's Threat Matrix for Kubernetes helps organizations understand the attack surface a Kubernetes deployment introduces to their environments. This ensures that adequate detections and mitigations are in place. By covering over 40 different attacker techniques, defenders can learn about Kubernetes-specific mitigations and controls to deploy to their environments. In this session, we will explore the MS-TA9013 Host Path Mount technique, which is commonly used by attackers to perform privilege escalation in a Kubernetes cluster. Attendees will learn how attackers and defenders can: * Escape the container's host volume mount to gain persistence on an underlying node * Move laterally from the underlying node into the customer's cloud environment * Analyze Kubernetes audit logs to detect pods deployed with a hostPath mount * Deploy an admission controller that prevents new pods from using a hostPath mount

Mental health has been in the news quite a bit lately. Dozens of U.S. states are currently suing Meta for contributing to the youth mental health crisis by inserting addictive features into their products, while the U.S. Surgeon General is touring the nation to bring awareness to the growing epidemic of loneliness and isolation. The country has endured periods of low national morale, such as in the 1970s when high inflation and the energy crisis worsened public sentiment following the Vietnam War. The current mood, however, feels different. Gallup recently reported that national mental health is at an all-time low, with few bright spots to lift spirits. To better understand how Americans are feeling and their attitudes towards mental health in general, ThinkNow conducted a nationally representative quantitative survey of 1,500 respondents and found some interesting differences among ethnic, age and gender groups. Technology For example, 52% agree that technology and social media have a negative impact on mental health, but when broken out by race, 61% of Whites felt technology had a negative effect, and only 48% of Hispanics thought it did. While technology has helped us keep in touch with friends and family in faraway places, it appears to have degraded our ability to connect in person. Staying connected online is a double-edged sword since the same news feed that brings us pictures of the grandkids and fluffy kittens also feeds us news about the wars in Israel and Ukraine, the dysfunction in Washington, the latest mass shooting and the climate crisis. Hispanics may have a built-in defense against the isolation technology breeds, owing to their large, multigenerational households, strong social support systems, and tendency to use social media to stay connected with relatives abroad. Age and Gender When asked how individuals rate their mental health, men rate it higher than women by 11 percentage points, and Baby Boomers rank it highest at 83%, saying it’s good or excellent vs. 57% of Gen Z saying the same. Gen Z spends the most amount of time on social media, so the notion that social media negatively affects mental health appears to be correlated. Unfortunately, Gen Z is also the generation that’s least comfortable discussing mental health concerns with healthcare professionals. Only 40% of them state they’re comfortable discussing their issues with a professional compared to 60% of Millennials and 65% of Boomers. Race Affects Attitudes As seen in previous research conducted by ThinkNow, Asian Americans lag other groups when it comes to awareness of mental health issues. Twenty-four percent of Asian Americans believe that having a mental health issue is a sign of weakness compared to the 16% average for all groups. Asians are also considerably less likely to be aware of mental health services in their communities (42% vs. 55%) and most likely to seek out information on social media (51% vs. 35%).

From their humble beginnings in 1984, TED has grown into the world’s most powerful amplifier for speakers and thought-leaders to share their ideas. They have over 2,400 filmed talks (not including the 30,000+ TEDx videos) freely available online, and have hosted over 17,500 events around the world. With over one billion views in a year, it’s no wonder that so many speakers are looking to TED for ideas on how to share their message more effectively. The article “5 Public-Speaking Tips TED Gives Its Speakers”, by Carmine Gallo for Forbes, gives speakers five practical ways to connect with their audience, and effectively share their ideas on stage. Whether you are gearing up to get on a TED stage yourself, or just want to master the skills that so many of their speakers possess, these tips and quotes from Chris Anderson, the TED Talks Curator, will encourage you to make the most impactful impression on your audience.
