Overview of this book

This book is an exhaustive overview of how the Appian Low-Code BPM Suite enables tech-savvy professionals to rapidly automate business processes across their organization, integrating people, software bots, and data. This is crucial as 80% of all software development is expected to be carried out in low code by 2024. This practical guide helps you master business application development with Appian as a beginner low-code developer. You'll learn to automate business processes using Appian low-code, records, processes, and expressions quickly and on an enterprise scale. In a fictional development project, guided by step-by-step explanations of the concepts and practical examples, this book will empower you to transform complex business processes into software. At first, you’ll learn the power of no-code with Appian Quick Apps to solve some of your most crucial business challenges. You’ll then get to grips with the building blocks of an Appian, starting with no-code and advancing to low-code, eventually transforming complex business requirements into a working enterprise-ready application. By the end of this book, you'll be able to deploy Appian Quick Apps in minutes and successfully transform a complex business process into low-code process models, data, and UIs to deploy full-featured, enterprise-ready, process-driven, mobile-enabled apps.

A first simple process

As our application is about a fictional process in a fictional company, you will need to model a small process that creates an invoice we can then use in an invoice validation process.

Creating the model

Just like any other object in Appian, you create a new process model with the NEW button in Appian Designer:

  1. You will need to enter a name (following the naming convention) for process models:
    <PREFIX> This Is My Process Model Name
  2. A good name would be IVP Create New Invoice.
  3. Click the CREATE button and accept the default values in the security settings. Then, Appian Process Modeler will open.

We already had a look at the Process Modeler in Chapter 3, Building Blocks of Appian Quick Apps, but this time, we will take a closer look:
