The Data Science Life Cycle

End-to-end projects involve real-world problems which you solve using the 6 stages of the data science life cycle:

  • Business understanding
  • Data understanding
  • Data preparation
  • Modeling
  • Validation
  • Deployment

Here’s how to execute a data science project from end to end in more detail.

First, you define the business questions, requirements, and performance measurement. After that, you collect data to answer these questions. Then come the cleaning and preparation processes to get the data ready for exploration and analysis. These are the understanding stages.

But we’re not done yet.

Next comes the data preparation process. It involves the preprocessing and engineering of the features to prepare for the modeling step. Once that’s done, you can train the models on the prepared data. Depending on the task you are working on, you can do one of two things:

  • Deploy the model on a live server and integrate it into a mobile or web application; then, monitor it and iterate again if needed, or
  • Build dashboards based on the insights extracted from the data and the modeling step.

That wraps up the data science life cycle. Before you start working, you need some ideas for a data science project.

For starters, select a domain you are interested in. You can choose one that fits your educational background or previous work experience. This will give you a head start as you will know the field.

After that, you need to explore the common problems in this domain and how data science can solve them. Finally, choose a case study and formulate the business questions. Only then can you apply the life cycle we discussed above.

Now, let’s get started with a few project ideas.

Detection of Metallic Surface Defects

The last entry in our list of data science project ideas is in the manufacturing and heavy industries domain.

Quality control procedures are used to identify defects in products during the production phase of manufacturing. With the help of defect detection systems, they can be automated and improved.

Project Overview

Flawed products can result in substantial financial losses, so defect detection is crucial in manufacturing. Although human detection systems are still the traditional method employed, computer vision techniques are more effective.

In this example, we build a system to detect defects in metallic objects or surfaces during different phases of the production processes.

The types of defects can be aesthetic, such as stains, or potentially damaging the product’s functionality, such as notches, scratches, burns, lack of rectification, bumps, burrs, flatness, lack of thread, countersunk, rust, or cracks.

Since the appearance of metallic surfaces changes substantially with different lighting, defects are hard to detect even using computer vision. For this reason, lighting is a crucial component in solving such types of data science problems. Otherwise, the methodology of this project is standard.


  • Collect the metal surface defects dataset
  • Data cleaning and exploration
  • Feature extraction
  • Train models for defects detection and classification
  • Deploy the model into production on an embedded system
  • Monitor the model in production and iterate

Expected Output

A deployed model on an embedded system that can detect and classify metallic surface defects in different conditions and environments.
