E-commerce both impacts - and is impacted by - many enterprise departments that have their own KPIs, budgets, decision-making rules, and objectives. Departments include sales, marketing, IT, finance, logistics, procurement, security, HR, legal, and more. Major changes, like implementing enterprise e-commerce platforms or significant changes in business processes, usually require substantial energy and time.
International variability creates an additional challenge on top of organizational complexity. Involving more regions or countries in an e-commerce solution adds extra stakeholders, local laws, customs. For example, local tax laws (which may impact pricing), legal requirements and practices, HR specific, cultural differences are all areas enterprise organizations need to consider during their e-commerce planning.
The complexity of enterprise IT is often a result of past business growth, acquisitions, and mergers of IT-departments. Enterprise IT infrastructures manage a mix of software, legacy enterprise e-commerce solutions, and a large variety of local and industry-specific software (like accounting, legal, ERPs etc.).
All this creates challenges for enterprise companies that must be mitigated by adequate architecture planning.
