Triangulation can help sustaining solutions and strengthening analysis.
When your organization faces a problem, sooner or later, there will be an action plan in place to abet its elimination. The inconvenient truth about solutions is that they have long tails. Very, very few solutions actually stick. Most of them seem to be gone in months, sometimes even weeks and the problem bounces back. Yes, I’m talking about lack of permanence to the actions taken to improve performance.
There are several theories and in-depth research but, from my experience, I can say that things haven’t changed much in the last 2 decades. Whether it’s automation, change management, top-down push, leadership sponsorship, incentives, rewards, recognition or culture fix, all of them are marked by only a certain success rate.
My other post, On recurring problems, 3L 5W & what’s wrong with it… explains a method to identify system level root causes. Triangulation can be used for validation of root cause and to evaluate the effectiveness of any solution.
Validation through Triangulation
Triangulation is a method that involves combining multiple sources or methods to validate an analysis or its outcomes. We are used to taking a second opinion from another medical professional before committing to an incisional treatment. That is an everyday example of triangulation. The origin of triangulation dates back to Greek civilization. In the last 2 centuries, it is very commonly used in maritime navigation, civil engineering and surveying, where it relies on sound trigonometry. In fact our GPS uses this very same principle to establish the lat-long of a location. Triangulation is also a very popular research method to validate results, findings and even for monitoring the sustenance of interventions, such as social welfare initiatives.
In business while validating root causes, triangulation comes very handy. If we can validate the root cause by more than one means, it strengthens our analysis and confidence in our actions. Financially too, it makes sense, as ROI is higher.
I consider Triangulation as it can also generate new and credible findings about a situation or phenomenon and can create new ways of looking at a situation or phenomenon.
Interestingly, it helps to overcome human behavioral bias, which is the biggest spoiler when it comes to organizational deployment. It helps to explore and explain complex human behavior using a variety of methods and observers to offer a more balanced explanation for a phenomenon.
Customer Attrition Example for Triangulation:
Let’s say, your organization faces unusual customer attrition. In general, you will collect and analyze data of customer activity by segments, such as customer journey, cart abandonment, milestones or events, complaints, etc to identify the reasons for customer attrition. Using triangulation, you can consider parallel methods such as customer interviews and front line employee interviews. You will independently gain insights from these 3 different methods viz., data, customer interviews & employee interviews to validate the outcomes. The results can either converge, complement or diverge from each other.
Interpretation of Triangulation Results
When all the three sources conclude that customer attrition is because of poor product support, we call this Convergence. That is, the results of the different methods lead to the same conclusion.
When all the three sources conclude that the customer attrition is because of poor product support, but in the customer interviews, we learn that customers prefer self-service which is a weak link of your product line, then triangulation has led to Complementarity.
When the three sources provide different outcomes, one pointing towards product support, another towards pricing and third towards customer behavior, then we are in a stalemate or Divergence. This is a concerning situation as it either highlights issues with the methods or with the very problem itself.
Triangulation Options
Depending on the objectives, triangulation can be done at different levels:
Data Triangulation – Using different data sources to validate. Ex: Customer activity database vs Customer Satisfaction database
Method Triangulation – Using different methods to validate. Ex: Data Analysis Vs Customer Interviews
Investigator Triangulation – Using different individuals to validate there by eliminating appraiser bias
While triangulation offers many benefits, you have to be careful in selecting the right methods and planning the analysis. In general, it can consume more time that quick action mode, but will reduce failures, increase sustenance and success rates.
You can also consider triangulation for verifying sustenance of initiatives, selection of vendors or new employees
3L 5Why Analysis is synonymous with Root Cause Analysis nowadays with most organizations having knowledge and know-how to perform 5 Why analysis. Most leaders encourage their leaders to use 5 why analysis to identify the root cause. That’s the good news!
Now the bad news 🙁 Most of the 5 Why analysis are incomplete and provide only tactical means to the current situation. They hardly look at underlying system level causes. If you don’t agree, list down all those problems in your organization that have been occurring for more than 5 years now, manifesting itself in some form or the other, in spite of a series of efforts year on year to arrest it. I have noticed that after some time, there is an innate acceptance in the organization that this problem is like the seasonal flu, it will keep coming again and again, we can’t do much other than taking precautions and facing it’s aftermath. In corporate, such perennial problems start off a mill of finger pointing rituals targeting other functions, individuals, company policy, customers, and even competition.
A comprehensive 5 Why Analysis should identify the systemic root cause of any problem. Some problems don’t need deep analysis at system level. Depending on the severity and occurrence of a problem, it should be possible to prioritize energies in identification of System level root causes wherever required.

3L 5Why analysis, represents 3 Level 5 Why analysis performed around the same symptom. The 3 levels of the 5 Why analysis implies, performing 3 different 5 why analysis on the same problem from 3 different perspectives –
Specific to the problem
Specific to the detection mechanism
Specific to the systemic issue
Here’s is how I use this method with my client projects and for coaching teams during my engagements (and it’s a little different from what others do with 3L 5 Why):
Level 1 – Specific to the problem – Perform 5 Why analysis for the issue on hand. It can be related to customers, regulators, safety, quality , productivity or any other significant failure. Usually this is done by the people closest to the processes in question, essentially the doers and immediate team leaders. The purpose of this level 1 5 why analysis is to identify the root cause for why the problem on hand occurred. For ex: Lets say, your regulator has fined you for non-conformance in a standard laid out by them. Here, our focus will be on : Why did we get fined now?
Level 2- Specific to the detection mechanism – Ideally this level of analysis has to be done by managers. They have laid out processes, controls, checks and balances to ensure critical issues are identified before it goes outside the organization. So the focus of this level of 5 why root cause analysis will be to identify the root causes for why the detection system allowed defects to pass downstream. Hence addressing this area will strengthen the control and governance system. For ex: Why did the transactions escape the automated checks, human checkers, approvers, auditors, process owners, etc
Level 3 – Specific to the systemic issue – The last and highest level aims to look for systemic deficiencies that lead to the problem. From my experience, this requires a very good understanding of the entire value chain. Actually it also requires a candid acceptance of flaws in the enterprise such as culture issues, process deficiencies, silos, resourcing gap, ineffective leadership, etc. Ideal for senior leaders to deep dive to identify system level root causes. From my experience, this is best done at periodic intervals by combining the study of several similar L1 and L2 failures. Most of them converge to a handful of common system level root causes. Unfortunately, the hard hitting reality is that these are conveniently ignored. For ex, in the case of compliance issue we touched earlier, an example of system level cause is, employees are held accountable for their mistakes and it directly impacts their growth and C&B; And so most of them wish to cover up anything that occured, even if it was inadvertent.
There are several practical strategies that need to be developed to improve the effectiveness of 3L 5 Why analysis depending on culture, know-how, sector, etc.
Another important missing link to 3L 5Why analysis is the data based validation. It is almost impossible to get to the root cause by merely brainstorming. An ideal approach would be to use a triangulation method.
