What is measured

A multi-disciplinary, cross-functional culture reduces digital waste by helping target unnecessary creation and duplication. A sustainable digital culture questions needless creation, collection and tracking. It focuses on durability. Key to waste reduction is establishing clear lines of responsibility for data and ensuring everything is properly maintained. Reuse and sharing should be prioritized and the overall metricsshould focus on use and usefulness, not production, launch and leave.

2. Responsibility
3. Durability
4. Creation, collection, tracking
5. Reuse

How audit will be carried out

Three core activities will be involved in the Digital Waste Audit:
1. Management interviews
2. Employee survey
3. Website review

Manager interviews

Structured interviews with appropriate managers mainly covering culture, communication, and digital device management. The questions are weighted based on overall importance, and each question can get from zero to 5 based on how well the answer complies with the optimal answer.


Employee interviews

Finding out what employees think about the organizational culture and how able they feel they are to work in a sustainable manner.

Website review

There will be a detailed technical review of the website to identify areas of waste. Some of this will be automated, some will require review, and some will involve interviewing a technical expert within your organization.


1. An overall rating from A (excellent) to E (very poor).
2. Individual ratings for:

a. Culture
b. Devices
c. Website
d. Communication

3. Key findings: What were the most striking things that were discovered.
4. Key recommendations: Clear and precise recommendations in relation to how to reduce digital waste.
