Grace Lau

Hello, I am Grace. I am an organizational-psychologist and organization development practitioner. I believe that, within any complex system, there is liberating power for innovation, learning and change – quite like how a seed that fell in-between rocks can grow into a flower, or perhaps into a Banyan tree. I am based in Hong Kong and work
internationally, particularly in Asia.

I became acquainted with Perspectivity through Han Rakels and Han Verhoeven. I like Perspectivity’s participatory approach in dealing with issues in complexity. The approach to ask open ended question and look every time at a situation with curiosity and openness is appealing in Perspectivity’s approach. Perspectivity is also working sector wide in society including NGOs, communities, businesses and governments in looking for sustainable solutions. People working with Perspectivity are committed, passionate and look at a holistic way on change and development.

I hope to contribute to Perspectivity’s approach by providing my expertise in participatory video and filmmaking. I am combining the art of filmmaking with community development. This approach fits to the approach of Perspectivity on how to deal with issues in complexity involving actors from different levels and contexts.

Prototyping and a participatory approach and application of data science in analysing and solving complex problems … yes, that makes my heart beat faster.

I have an academic background in Informatics (both technical and administrative). After my studies, I have contributed to proper use of ICT products and services working in different positions in “softer” sectors such as development cooperation, education and health care. In these sectors, it is striking that ICT (and nowadays data analysis) was and is often a catalyst of change. That makes ICT such a wonderful field for me.

I have worked for companies, government institutes and NGOs in the Netherlands, Tanzania, Uganda, Ethiopia, Zimbabwe, Mali and Surinam. My work generally focuses on the intersection of organisational change, policy, strategy and computerisation.

Lately, I have become fascinated by the ‘new’ data science. With Garage2020, an organisation with the ambition to stop current youth services through new technology such as virtual reality, robotics, data analysis, I have conducted an analysis and based on that we have developed applications that, amongst others, support the – often complex – decision making processes by a group of youth services professionals. One of these applications, the app “Extra Teamlid” (extra team member) has won several prizes in the Netherlands, such as the E-health award during the Dutch Design Week in Eindhoven (2018) and two categories during the Spin Awards (2019).

I like to work on projects where ICT and/or data are used to realise change, preferably as disruptive as possible. In 2020, I will amongst others work with Fairphone, a social enterprise with the ambition to realise change in the telecommunications sector. The Fairphone is a smart phone that is produced with ethically sourced materials (tin, tungsten, gold, etc.) and has a modular technical design to lengthen its lifetime. Fairphone will never surpass its competitions in terms of sales but that is not the goal. Fairphone wants to increase the awareness for sustainable and ethical production in the smart phone industry and inspire other companies to also develop modular phones with ethically sourced materials.

Next to this, since 2011 I have been teaching for on average two hours a week at the Virtual University of Uganda for the MSc programme ICT4development. Normally I teach at a distance (from my house in Amsterdam), but now I am able to spend more time in Uganda for, for example, coaching students and supervising graduation projects.

Making it possible for people to connect with themselves. With others. With the context. And with the purpose. This is what I always wanted to do. And what is driving me forward.

I was born in the (later to become) Czech Republic, to the times of societal shift from communism to a liberal society. And I believe that this context has significantly shaped my life. In addition, during my studies of Psychology and of Organizational Change and Consulting, I developed a passion for the field of psychotherapy and leadership, and living in different corners of Europe made me appreciate the beauty of cultural varieties.

All in all, I am fascinated by all the different realities that people live.

And these can be often improved! I deeply believe in the power of self-awareness, in generative dialogue and in the appreciative exploration of others’ worlds.

I work with Perspectivity on different projects as a Young Enterprise member since spring 2018.

I was involved in Perspectivity from the start. Perspectivity changed my life. I am part of the Network, and I feel part of a network of people, who give me joy, inspiration and knowledge to improve the way I work and the way I communicate with people.

I work as a teacher, writer and adviser on education with a focus on education and sustainability. One day a week I teach Biology to young people with a migration background (Internationale Schakelklassen). Since 2016 we started a very successful and heartwarming project ‘Bijles voor de ISK’. Second grade students form my old school help ISK-learners to master Biology content. Another recent Perspectivity-related activity was a course ‘Sustainable Leadership’ for high school students in 2018 and the organisation of an ecofestival.

“My name is Nele and I’m proud to be part of the Perspectivity community. I am an independent consultant in the field of Monitoring and Evaluation for Development for three years now. After graduating with an MSc in Information Systems, I have specialised over the years in the design and implementation of monitoring and evaluation systems in complex contexts. I’ve held various positions within the public and international development sectors, such as with War Child Holland and Oxfam Novib. My first job was at IICD, where my colleague Lisette Gast introduced me to the field of M&E.

In the last three years I’ve cooperated with Perspectivity in many ways and with different people such as Lisette, Anne, Han and Tereza. These assignments always entail Sprockler, as I’m an enthusiastic user even since it was a prototype. I started using Sprockler already during my time at Oxfam Novib in 2016 for projects in Afghanistan and Pakistan. Recently, I’ve conducted a Sprockler baseline for a project in Uganda that promotes play-time for children. I often combine Outcome Harvesting with Sprockler, and now I’m focused on developing an Outcome Harvesting module in the Sprockler tool in the near future.”

My Perspectivity journey started during my first and only philosophical crisis to date. In 2006, I signed up for a Master in International Relations & Diplomacy after completing five years of engineering. I arrived in my new town Leiden confident that I, as a solid engineer, would teach “those alphas” about true science. I had learnt in Delft about the unquestionable laws of nature. Something is true, or it is not. In Leiden, on the contrary, I soon discovered that my engineering toolbox was insufficient to understand political and social systems. The laws of nature do not hold: all actors view the system differently, their views drive their behavior, and their behavior defines the system.

It was unsettling for a while to realize that there was ‘no single answer’. It gradually made me realize the importance of being able to see the world through someone else’s eyes: the activity of seeking perspective.

Through my friend and former colleague Hein Oomen, I met Hans Keijzer who founded Perspectivity. At the time, he had little more than a vague plan: to do something with dialogue and scenario-thinking and improve the world. I got intrigued because of his unconditional commitment behind that vague plan.

Today, I am chairman of the board of the Perspectivity foundation and have been part of an amazing growth journey: growth for Perspectivity as an organization, and in parallel lots of personal growth for myself.

It is great to be part of a group of people showing great commitment, who are open in their interactions and have a common goal: how do we improve our collective navigation of the complexity of modern life? I am learning every day.

It was April 2012, when Perspectivity first got to me. Unsuspectingly, I went on a corporate get-away with my FMO (the Dutch development bank) colleagues to Texel. Just for fun – which was called ‘team-building’ by then. We had a nice day of exploring the little island, full with adventurous games and challenging assignments – all teams with the ambition to win. Nobody had expected that at the moment we all dozed off a bit, the next day, the real adventure and actual mud throwing hadn’t even happened yet. That was when we started to play the game: the Perspectivity game.

I was stunned, forceless, frustrated, manipulated, furious, happy and releaved all in only one hour. I was thunderstruck by the fact that me and my fellow colleagues, all in the environmental & social analysis departement of the bank, were simply unable – and unwilling – to bring the game to a good end. Which is quite surprising, since we all by now know – after playing the game only once – that ‘a positive result’ is a feasible option. Which underlying mechanisms of human behaviour make it so hard to reach this coveted positive result? Unfortunately, for too many reasons, I presume.

Anyway. I switched jobs from FMO to Intermin. Without knowing Eelke and his background in Perspectivity yet. What are the odds? I met Eelke, Joep and Maarten, and the latter invited me to come to one of the Perspectivity weekends. As soon as I crossed the doorstep of the dining room in De Hoorneboeg, I felt extremely welcome. Surrounded by people who really care for a cause or two, and who care for each other. People who all like abstract, conceptual and intellectual talk 🙂 People who remember where their last conversation ended, so where to continue.

Everything you just read may sound simple. But it is not. Being such a nice group of people, finding each other – digitally & personally, intellectually & emotionally – is quite complex.
