Value

Time-focused

Easy transition of the Project

Repeatable and validable

Lifecycle

1. Discovery:

Learn

the business domain to determine the general problem type and learn from the past relevant experience;

Access

available technology, raw data, right people and time scope

Formulate

initail hypothesis,

2. Data Preparation

Prepare work space (the analytic sandbox )

Preform ELT(Extract Load Transform Data)

Understand the data: ? Compare What you needVSwhat you have

Clean & Normalize data

Decriptive Statistics ?& Visualize to have an overview of the data qulity

3. Model Planing

Select methods based on data volume and structure, hypothesis and bussiness objectives

Determine workflow of candidate tests

Identify modeling assumptions

Explore dastaset and select significant variables via certain dimension reduction method

4. Model Building

Split the availble data into training data and test data

Get best environment to run the model(fast hardware, parallel)

5. Communicate Result

Interpret the results to identify key findings

Quantify bussiness value acording to the customers

6. Operationalize

Run a pilot to assess the benefits

Deliver and excute the final result in operation

Define process to improve the model as needed
