Navigating the legal, commercial and human complexities of major projects has taught Achala Ariyarathne that effective leadership begins with understanding what people are trying to achieve. As Founder and Managing Partner of Dimean Law Chambers and Managing Director of Dimean International (Pvt) Ltd, she brings this perspective to work spanning construction disputes, project finance, foreign investment and business development.
Her foundation in dispute resolution as a quantity surveyor and claims management officer established a core principle: legal strategy must be rigorously grounded in operational reality. Working alongside international project management teams, institutional investors, regulators, and entrepreneurs has refined her mastery in strategic negotiation, active listening, and decisive stewardship through high-stakes uncertainty.
Her leadership approach is defined by the powerful convergence of her roles as an Attorney-at-Law, entrepreneur, corporate leader, and mother. Absolute professional discipline sharpens her judgment, commercial adversity has forged her resilience, and motherhood has deepened her strategic patience and empathy. She views these integrated responsibilities as the bedrock of her executive presence.
Today, her strategic focus centers on cultivating independent, high-caliber thinkers within her team, maintaining unyielding operational standards, and proactively preparing her firm for evolving global market demands. She measures success by the powerful alignment of professional ambition and core identity. In this interview, she reflects on the command, conviction, and pivotal choices required to construct both an enduring enterprise and a meaningful life.
Q: You wear many crowns as a lawyer, entrepreneur, leader and mother. What do they mean to you, and which has shaped you most?
I do not think of titles alone, although I have been fortunate enough to earn some along the way.
To me, a crown represents responsibility: the roles we grow into and the strength, discipline and sometimes sacrifice required to carry them well.
I am a mother to two beautiful girls, and that role has shaped me most deeply. Motherhood changes your understanding of responsibility because your decisions are no longer only about you.
You learn patience, prioritisation and strength. It has influenced how I look at people and lead.
Professionally, I am a lawyer, entrepreneur and the founder and managing partner of my own law firm. Building DIMEAN has required perseverance, consistency and responsibility for my team, clients and the direction in which we grow.
These crowns do not exist separately. The patience I learnt as a mother has made me a better leader. The discipline required in law has made me more structured elsewhere. Running a business has taught me resilience and perspective.
I find it difficult to choose one crown that defines me. Each has shaped a different part of who I am. Wearing many crowns is not about how many roles you hold, but how responsibly and authentically you carry each.
Q: How have law, business and major projects shaped your leadership?
My leadership has been shaped as much by experience outside the courtroom as by legal practice.
Before and alongside developing my legal career, I had exposure to quantity surveying and claims management in road development projects. My legal work later involved infrastructure development, construction disputes, project finance, foreign investment and property. Working with engineers, investors, entrepreneurs, regulators and corporate executives exposed me to different cultural and professional backgrounds.
I learnt that expertise alone is not enough. Understanding the law must be accompanied by understanding the business, project, people and what each party wants to achieve.
Negotiation taught me to listen carefully, ask questions and understand concerns beneath the positions people present. Patience is extremely important.
Running my business brought financial highs and lows, unexpected challenges and difficult decisions. You cannot allow every difficulty to become a crisis. You must remain calm, decide what can be controlled and move forward.
Experience has also made me more comfortable with change. Leadership requires making the best decision with available information, accepting responsibility and adjusting when circumstances change, rather than waiting for complete certainty.
Q: How do you balance professional ambition, motherhood and personal identity?
I have never believed balance means giving everything equal time.
Sometimes my profession and business needed more of me; at other times, my family came first. Being a mother of two while building a legal career and running my firm has required difficult choices. Some days I managed everything as I wanted; on others, I accepted that I was doing my best.
Women can be particularly hard on themselves. We expect to be fully present professionally and as mothers, available to everyone, while finding time for ourselves. When we cannot do everything perfectly, we feel we have failed.
For me, balance means knowing what needs me most at a particular moment and giving it attention without constantly feeling guilty about what I am not doing elsewhere.
Priorities change. Children need different things at different stages, and businesses have seasons that demand more from you.
Remembering who I am beyond my profession keeps me grounded. I am proud of what I have built, but my career is not my entire identity. My children, family, values and the person I have worked to become matter just as much.
Q: How has leading an organisation changed your definition of leadership?
Earlier, I thought leadership was largely about competence: knowing answers, making decisions and solving problems.
There is a significant difference between being a good lawyer and building a good law firm. A lawyer focuses on the matter: understanding facts, analysing law, assessing risks and finding the best solution. Leading an organisation requires the same discipline but a wider perspective.
Today, I consider the firm’s direction, quality of work, people, client relationships and changes in the profession. Emerging practice areas, international relationships and technology’s impact on client expectations are increasingly important to my role at DIMEAN.
Leadership is not about making yourself indispensable. If everything depends on one person, you have built a dependency, not an organisation.
Developing people is now a central responsibility: giving them confidence to think independently, make decisions and learn from mistakes. That can be difficult when you are accustomed to responsibility for every detail, but an organisation must grow beyond its founder.
My leadership is less about having every answer and more about creating clarity, maintaining standards and enabling responsibility. Decisiveness matters, alongside listening, empathy and knowing when to adapt.
Q: What should future women leaders understand about ambition, courage and success?
Do not allow others to define what a successful life should look like.
Women face expectations about careers, choices, ambition and priorities. Trying to satisfy every expectation can leave you living a life that does not truly belong to you.
I have made bold professional and personal decisions without knowing how things would turn out. Carrying significant responsibility while raising two children and building my career shaped my understanding of courage.
Courage is not the absence of fear. Decisions can frighten you because something meaningful is at stake. Courage means acknowledging fear, deciding what you believe is right and moving forward.
Do not confine yourself to one definition. You can be ambitious and deeply committed to family. You can be a mother and build something of your own. You can succeed and later choose another direction. Success is allowed to evolve as you do.
Do not wait until you feel completely ready. Meaningful opportunities rarely arrive when you have every answer and no doubts. Prepare yourself, keep learning, trust the experience you have earned and have confidence to take the next step.
