PIDGraph

Redesigning the SaaS industrial application through comprehensive research

PidGraph is a state-of-the-art artificial intelligence (AI) backed tool that is used to digitize technical Piping and Instrumentation Diagram (P&ID) documents. The typical users are process engineers and project managers who specialize in drawing and using P&ID documents.

Business Challenges

Initial input from users and insights from stakeholders contributed to the identification of the current issue:

​

  • A steep learning curve attributed to inconsistencies in user flow and components.

  • Insufficient information for frequent user tasks.

  • Inconsistencies between user needs and available functions.

  • Comparatively more challenging to use when compared to competing products.

Objectives

Recognize the prevalent challenges users encounter when utilizing PIDGraph and propose alternative strategies to enhance the effectiveness of the manual drawing procedure.

Typical User

Typical users of PIDGraph perform the following roles:

  • Industrial Draftsman

  • Lead Draftsman

  • Project Manager

Typical responsibilities for PIDGraph users include the following:

  • Perform walk-down of piping and equipment assets

  • Conduct data collection/validation in the industry processing facility

  • Identify various types of piping, valves, equipment, and insulation

  • Read and markup various drawings including Piping & Instrumentation Drawing (P&ID), Isometric Drawing (ISO), Equipment Drawings & Area Maps

  • Create field sketches based on data collection

  • Use basic Windows operations including file management and Microsoft Office

  • Upload work to the Drawing Integrity Management System

100% need better interaction

50% need role based functions

25% need feature improvement

PIDGraph can be learnt over time. 

  1. Not easy to transfer properties 

  2. Complex symbol library​

  3. Missing important functionalities​

  4. Unintuitive interactions​

  5. Repetitive errors

Result

The updated PIDGraph design has notably enhanced the quality rating as per the User Experience Questionnaire (UEQ). Key elements that saw a substantial improvement, such as Attractiveness and Simulation, are closely tied to increased user motivation in utilizing the tool. This, from a business standpoint, correlated with the adoption rate.

While users initially view PIDGraph as a practical and easily learnable tool, the redesign result further enhances this aspect. For instance, the Dependability point addresses the initial issue of a steep learning curve.
