In large organizations, and public administrations in particular, Odoo integrators are often tasked with the implementation of elaborate business processes. In such organizations, one meets complex requirements such as fine-grained user roles and multi-step approval processes, based on many criteria (such as organizational structure, user-defined functions and permissions).

The scale and sophistication of such processes present specific challenges in terms of requirements capture, implementation, security and testing.

During this talk, business analysts will learn techniques to capture, document and test requirements for such complex business process, using UML statecharts.

Developers will learn how to translate such requirements in code that are:

• easy to review against requirements;

• easy to maintain and migrate across Odoo versions;

• secure, ensuring fine-grained user rights and permissions to trigger actions that are verified in all circumstances,  (views, xml-rpc);

• without business logic duplication.

The talk will be illustrated with examples from a large project at the Walloon Region Public Service, where Odoo is used for purchasing, asset and inventory management processes. Standard Odoo apps used include Purchasing, Invoicing, Inventory, as well as community modules for, e.g. Purchase Requests.
