There are three types of people that can help accelerate the adoption of new products or ideas: Connectors, Mavens, and Salespeople. Connectors make change happen through their large networks of people and connections. Mavens make change happen through sharing information and identifying new ideas and trends. Salespeople make change happen through their ability to build rapport and persuade others. The document provides questions to help identify whether someone has the traits of a Connector, Maven or Salesperson.

Try one of these eight smooth moves you can use to win their hearts and minds (plus an extra special bonus move to really get that lovin' feeling going strong.)

As we prove ourselves to be hard-working and competent people, we get more and more responsibilities and opportunities. The same thing happens with companies getting more and more demand for their services.
The problems arise when, at some point in time, we are forced by the limits of our time and resources to give up on something. Either we decide what that will be, or our circumstances will decide for us.
That is why companies have entire teams of people working to evaluate opportunities and demands coming their way, and politely but firmly saying “No” to those that don’t fit their big picture.
The goal of this presentation is to help you do the same!

Christian van Stom learned Scrum on the cusp of the dot com bubble bursting. He has led multi-functional teams across 3 industries, and technical, marketing, sales, customer service and operational squads.
An enterprise agile coach role lured him north to Brisbane, to the finance sector where he was to lead the transformation of a 300-person enterprise. Hear his real life account of the challenges and learning of embedding real agile ways of working in a highly acquisitive business, moving at an incredible pace run by an ex-serving, paratrooper legionaire.
Changing the way we change – leveraging a combination of Lean, Design, and S...Scrum Australia Pty Ltd
Lean & Agile have a shared orientation towards customer centricity, respect for people, and continuous improvement. When applied with the right intention to the appropriate context, both domains complement each other exceptionally well in solving complex business problems effectively and sustainably. Aginic and Nik Ilich from Fire & Flint collaborated in driving a principles-first approach to iteratively designing and implementing a transformative future state service onboarding journey for clients of Cerebral Palsy Alliance (CPA). Through a hybrid of lean & agile thinking, the team worked closely with key representatives of CPA, sharing the driver’s seat, to pragmatically deconstruct and deliver a vision for the future with strong agile-delivery foundations underpinning its execution.
In the first months of remote work due to COVID, I noticed a massive opportunity to learn from others, as a lot of conferences went online.
But then arose a problem in my capacity to absorb these learnings. So, I started my Creativity Journal and have never look back.
The natural constraints imposed by having a Creativity Journal ensure that I prioritise my attendance to online conferences, such as the Scrum Australia Lightning sessions and Creative Mornings talks. I take notes when I attend these insightful sessions; and then share the notes after the sessions.
Let me show you how you too can get the benefit of a Creativity Journal.
Are your retros boring, non-productive, and a waste of time? Come learn about 3 case studies of extraordinary retrospectives.
Retrospectives are the heart of the feedback loop, existing within an agile framework that fosters self-improvement.
Retrospectives lose value due to 2 reasons: they get boring or they have no value in terms of actionable items.
The first case will describe a team’s experience, organised at the Australian War Memorial in Canberra, Australia. A custom tour was developed that focused on “mateship”.
The second case will describe a team’s experience at the National Portrait Gallery in Canberra, Australia: a prototype team training based on Visual Thinking Strategies, VTS, usually reserved for 11-12 year old school children.
The third case will describe a leadership team’s experience at the Art Gallery of NSW in Sydney, Australia. A team of executive-level leaders learned about mindfulness techniques and taking the time off to appreciate art as a team.
I will describe how you can partner with a variety of resources, including government programs, that will enable you to do the same thing.
The predominant mindset around complex problem solving is decomposition; we inevitably jump to ways of ‘chunking up’ a solution. At Aginic, our experience of delivering hundreds of engaging data experiences is that this often misses a step that is crucial to creating compelling digital experiences: experimentation. In this talk we’ll describe how we have baked in experimentation to our ability to explore and navigate complex problem spaces and how this has helped deliver engaging outcomes for our customers.
This talk is a must for anyone tackling complex projects, particularly involving data.
People decide to go agile and then take on the task of hiring a coach. But if they don’t know anything about agile, how do they know what a good coach looks like? Here I take a look at what coaches should value over the many of the things that consultant coaches value.
Are you trapped in a hamster wheel of meetings, updating tracking tools, trying to keep stories progressing and generally being the “Scrum secretary” for everything that others are not doing themselves? Whilst you might be aware that this is not the most effective way to spend your time, you may not know how to transition out of this situation and what the more impactful activities are to transition to.
In this session we will explore what the most effective Scrum Masters and Agile Coaches focus on as well as some strategies for freeing up your time and building your skills in order to make a much bigger difference for your Scrum Team and surrounding organisation.
Situational Scrum Mastering: What the Scrum guide didn’t tell me about leadin...Scrum Australia Pty Ltd
This session aims to raise awareness about what it takes to successfully lead a team that is trying to be Agile. Santosh will share his personal experiences about challenges he has faced, and why it’s important for an effective Scrum Master to understand what their team needs in terms of leadership before they can successfully lead a team.
According to Paul Hersey, leaders need to adapt their behavior to fit a team’s readiness. Based this readiness level, which is determined by the team’s ability and willingness, a Scrum Master can opt for Telling, Selling, Participating, and Delegating their style of leadership.
In this talk, we will dive into specific things a Scrum Master should do when leading a team that has a different level of readiness. Ultimately, we will learn how a Scrum Master can help teams with limited confidence and abilities to become an agile team, leading them to maximise their agile-ness throughout.
If you are just starting a career as a Scrum Master are a seasoned veteran, or even an agile team member, and want to increase your understanding about leading teams that are trying to become agile, then this talk is for you.
A storm is defined as a disturbance of the atmosphere or the state of an environment, and life brings them in many forms and sizes. Some bring significant disruptions to normal conditions, while others destroy the existing structures and force a rebuilding. As humans we will experience various storms throughout our lives, with the aim of surviving them all.
We are so used to the occurrence of storms that preparing for them has become second nature. We have the technology available to us to help predict them, their size and intensity, so we know what to expect and plan accordingly. Best practices exist to manage the storms. However with climate change, it feels like there are more ‘freak’ one in a 100 year occurrences happening, which take everyone by surprise. The best practices lead to chaos. What’s the future going to hold and what can we learn today to in order to build our resilience for future storms? Do we reflect the shifting environment into our existing practices?
How do we apply these learnings from our life to an Agile transformation of an organisation?
On the horizon, a cyclone is growing in intensity and heading towards your organisation: to disrupt the existing paradigms. Everyone is scared and uncertain of what will survive, or will need to be rebuilt after the agile transformation has hit. What do we need to do to prepare for the transformation? How are we going to work together to build our resilience in the chaos of the cyclone?
How do organisations embrace the storm?

Outcomes such as “subscriptions increased by 20%” or “complaints regarding the upload feature reduced to zero” are what makes a real difference in our customers lives and hence to the company’s bottom line. When a team is delivering outcomes like that, there is no denying their performance and hence their value to the company.
Delivering outcomes comes from understanding our customers, producing an output that may result in an outcome and then validating if we have achieved the desired outcome. At the very least one of these cycles produces knowledge. The Lean Start-up by Eric Ries, clearly explained this cycle, unfortunately it did not explain clearly how we should design, set up, run or analyse our experiments. I have met many people who agree we should follow the Lean Start-up approach; however, there is rarely any consensus on the experimentation approach that will make it a reality.
In 2017 Australia’s largest independent game studio, Halfbrick Studios, embarked upon a mission to better understand their customer and experiment their way to renewed success. Fruit Ninja Fight is one of the results of that approach. In 2018 Australia’s largest Telco, Telstra, focused on “co-creation” with their customers through a series of experiments; delivering improved customer satisfaction and faster results than ever before.
This presentation shares with you my experiences of working with those two Scrum based organisations as they sought to improve their outcomes through Experimentation.
by Alan Taylor (Innodev)
Test Driven Development is an engineering concept with practices that has great benefit to business. For example, if your business wants to have idealised and revered products, you will have:
- an ability to deliver high quality products which keep up with the latest customer wishes;
- products which are constantly updated with the latest cool features; and
- ability to very quickly resolve any issues that do occur – and they do for even the best organisation
We will share with you why Test Driven Development is a pivotal tool in the fight to be one of those inspiring organisations. We will cover the practices at a high level and go into the outcomes of those practices. We will include not only how the business should benefit directly from them, but also how they provide indirect benefits for the team and the organisation. Every positive has some negatives, whether they are perceived or actual, long term or short term). We will touch on how they are like any form of exercise – they will be hard work at times, but afterwards the results will include fitter, stronger and faster teams able to delivery consistently better results.
As a manager or leader, you will be able to walk away with insight that will enable you to determine how TDD is worth following up in your domain.
As someone within the delivery team, you will leave with deeper understanding of how you, your team and your company can effectively benefit from Test Driven Development.

Do you always take the stairs? How to use your growth mindset to build smar...Scrum Australia Pty Ltd
by Jen Miller
This session introduces the concept of a Growth Mindset and its synergies to Scrum and Agile, through the sharing of examples I have experienced. Attendees will learn what the qualities of a Growth versus Fixed Mindset are and how to recognise them in ourselves, our teams, and organisations. Tips and techniques on how to introduce and promote a growth mindset and how it helps build smarter scrum and agile teams will also be shared, so attendees have practical tools to take away with them.
The concept of a Growth Mindset gained real visibility with Carol Dweck’s research and 2007 book Mindset: The New Psychology of Success. Her research looked at how children learned and faced challenges and problems thought to be beyond their age. Children who were excited to try something new, and learn while doing it, demonstrated what Carol Dweck called the ‘Growth Mindset’. The principles of Scrum align with this concept as they are founded on the empirical practices of try, inspect, and adapt. Seeking to continue learning and improving are characteristic of Scrum and the Growth Mindset. Being aware of, and practicing, the qualities of a growth mindset will make scrum teams and organisations stronger, more resilient, and adaptive in times of challenge and change.

Imagine you are a Mad Agile Scientist and have a diabolical experiment to conduct – what would happen if you exchanged the brains of a Product Owner and Scrum Master? Mwuhahahaha!!! How would the body of a Product Owner with the brain of a Scrum Master act? And vice versa?
Perhaps the Scrum Master would now treat the team like a backlog? This Scrum Master would be focused on value and maintaining a coaching backlog of team and person improvements. This Scrum Master is refining the team, crafting a group that delivers value.
And perhaps the Product Owner might treat the backlog like a team? Rather than backlog refining, they coach the backlog. They would be focused on nurturing, protecting, and empowering the backlog. The backlog might transform from an irritation into a labor of love.
Although this experiment sounds terrible, this change of perspective might be what you need to reanimate your dead team or backlog.
Join the fun and come learn what horrifying results await!

Have you ever sat through endless scrolling credits after a film, speechless, while you processed your thought and feelings? Hundreds, if not thousands, of those disappearing names contributed towards these profound moments of transformative experiences. Timeless films are excellent examples of deep collaboration between multidisciplinary teams of highly skilled craftspeople, working to create moments that transcend the audience to the story world and subtly move them through the journey of films’ protagonist/s.
Filmmakers are master collaborators that literally bring together teams of multidisciplinary casts and crews on the same page of the scrip. Great filmmakers challenge and inspire technicians to become artists and actors, to become immortals through the “power of the story”.
Many years ago, my screenwriting lecturer famously told us during our very first day at the film school, “One thing is certain about filmmaking, that everything you have planned will need to change because it will rain tomorrow”. Filmmakers mastered the art of embracing uncertainty many decades ago, when there were no weather apps, by being truly agile.
In this talk, I will draw from my lifetime of study and exploration of the art and craft of filmmaking. I will demonstrate, using examples from classic films, how motivated and inspired multidisciplinary teams collaborate to bring the vision of a cinematic project to life and transcend audiences around the globe to the story world. I will share what leaders can learn from masters of the ultimate collaborative art of filmmaking.

Team Dynamics is like an unconscious force that influences team behaviour, reactions, and performance. Problems and solutions, from my experience, will be packed into a nice presentation, but the most exciting part will be the “Time to play” where we will face real problems and discuss how to solve them. Games like Blame game and responsibility game will be played and discussed.

This session is a structured walk-through the ideas around collaboration. I’ll be introducing key ideas and then leading participants through a workbook of eight questions that help people understand collaboration, why it is important and how they can take action to increase collaboration at their workplace.
People like the idea of collaboration, but have fuzzy ideas about what it is and what good collaboration looks like. This will help them think about collaboration in a more structured way and see opportunities for improvement in their own context.

How to make friends and influence people: Maximising the impact of your Sprint Review
1. A Maven, Salesperson or
Connector?
There is a small percentage of early adopters that
Gladwell describes as Connectors, Mavens and Salesmen.
Through leveraging the strengths of this group, Product
developers can really accelerate uptake. You can also use
this thinking on internal projects when trying to get
support, you’re always going to have a group of people
that resist even the most benign change. Use your early
adopters and visionaries to help communicate and lead the
way.
Mavens make change happen through information and
ideas. They are the ones who tell Connectors about
what’s hot.
Connectors make change happen through people. The
strength of Connectors is that they know and keep in
touch with many people. They also tend to associate
with other Connectors.
Salespeople make change happen through persuasion.
They can build instant rapport with another person
and gain their trust.
Questions What type are you?
Do you know a lot of
people?
Do you like people?
Do you tend to remember
peoples’ names?
Do you enjoy going to
parties and meeting new
people?
If you answered ‘yes’ to
four or five of these
questions, you are a
Connector.
What type are
you?
2. Do you collect
acquaintances?
Do you enjoy reading junk
mail?
Do you seek out the
specials in your local
supermarket?
Do you tend to watch trends
and know what’s ‘in’?
Do you study the market
before buying a new gadget?
Do you tell your friends
about special deals?
If you said ‘yes’ to four or
five of these questions, you
are a Maven.
Do you find it difficult to
sit still when hearing good
dance music?
Do you have a loud laugh?
Do you touch friends when
you talk with them?
Are you good at seduction?
Do you like being the
centre of attention?
If you answered ‘yes’ to
four or five of these
questions, you are a
Salesperson.
If you picked inconsistent answers, or had trouble picking answers at
all that’s ok! You have skills and are comfortable in all areas.
