The Aiken Pyramid: Turning Data into Decisions
The Aiken Pyramid shows how raw data becomes actionable insight. Data forms the base, organized into information, which leads to knowledge through analysis. At the top, wisdom enables informed decisions. By following this framework, organizations can transform everyday data into meaningful insights, guiding smarter strategies and turning numbers into real business value.
The Aiken Pyramid supports organizations in managing their data by providing a structured framework that shows how raw data is transformed into valuable insights and decisions.
It illustrates the progression through levels:
- Data – Raw, unprocessed facts collected from various sources
- Information – Data that has been processed, cleaned, and organized
- Knowledge – Understanding patterns, relationships, and meaning in the data
- Wisdom – Using knowledge to make informed decisions and take action
By using the Aiken Pyramid, organizations can:
- Understand where their data currently sits in the hierarchy
- Identify what processing or analysis is needed to move data up the pyramid
- Align data management, analytics, and decision-making efforts
In essence, it helps organizations turn data into actionable value rather than leaving it as unused raw data.

My Story
From Curiosity to Craft: My Journey in Technology and Analytics
My name is Nuwan Hettiarachchi, and my journey has been guided by curiosity, service, and a strong belief in using technology to create meaningful impact.
I began my professional path working closely with data, systems, and people. Early on, I realized that I enjoyed solving practical problems—especially those where analytical thinking and real-world needs intersect. This led me into data analytics, automation, and software development, where I’ve spent years building tools that improve accuracy, efficiency, and decision-making.
A defining part of my journey has been 10 years of volunteer teaching at a charitable organization. Teaching reinforced my belief that knowledge is most powerful when shared. It strengthened my communication skills, patience, and ability to break down complex ideas—skills that continue to shape how I design systems and collaborate with teams today.
Professionally, I’ve worked across data analysis, reporting, and application development. One notable experience was developing a Human Resources appraisal system over two years using Visual Basic and SQL Server, where I translated business rules into reliable, user-friendly software. Projects like this deepened my appreciation for clean data, thoughtful design, and systems that support people—not just processes.
Over time, my work expanded into Python, SQL databases, analytics, and automation, with a growing focus on data integrity and insight-driven solutions. I enjoy building tools that reduce manual effort, surface meaningful patterns, and enable better decisions.
Outside of work, I value balance and mindfulness. I enjoy hiking, traveling, kayaking, and spending time in nature—activities that keep me grounded and curious.
Today, I’m focused on contributing within data science and analytics–driven environments, continuing to learn, mentor, and build solutions that are practical, ethical, and impactful.
