An effective way to begin a clustering exercise is as follows:

1. Define the Problem: Clearly define the problem you are trying to solve. Understand the data you have and what you want to achieve by clustering it.

2. Collect and Prepare Data: Gather all the necessary data that you need for the clustering. This could be from various sources. Once you have the data, clean it and prepare it for the clustering process. This could involve removing any outliers, handling missing data, and normalizing the data.

3. Choose the Right Clustering Algorithm: There are various clustering algorithms available like K-means, Hierarchical, DBSCAN, etc. Choose the one that is most suitable for your data and problem.

4. Determine the Number of Clusters: This is a crucial step in the clustering process. Various methods like the Elbow method, Silhouette method, etc., can be used to determine the optimal number of clusters.

5. Run the Clustering Algorithm: Once you have determined the number of clusters, run the clustering algorithm on your data.

6. Analyze the Results: After the clustering process, analyze the results. Check if the clusters formed make sense and if they help in solving the problem you defined in the first step.

7. Iterate: Clustering is an iterative process. You might not get the desired results in the first go. You might have to go back, tweak some parameters, and run the clustering again.

Remember, the effectiveness of a clustering exercise largely depends on the quality of your data and the appropriateness of the clustering algorithm used.
