Horizontal Integration and Business Partnering

Horizontal integration sits at the heart of AC 3.2 for 5CO01, and this video addresses it through the business partnering model developed and popularised by Dave Ulrich. The video examines how that model repositions HR professionals as embedded consultants within business units rather than as centralised administrators, and how it operates through what is commonly described as a three-legged structure comprising Business Partners, Centres of Excellence, and Shared Services. Each element of that structure — specialist teams covering areas such as reward, talent acquisition, and learning and development alongside transactional shared services — is covered in terms of how it enables strategic focus at the business partner level.

The video moves from the model itself into the practical, function-by-function connections that horizontal integration requires. It covers the people practice relationship with finance, including workforce budgeting, headcount planning, and investment cases for people initiatives, as well as the connection with operations and production environments where scheduling, absence control, and skills development carry direct operational consequences. Sales and commercial functions are addressed through the lens of incentive design, sales capability development, and employer branding alignment, while the IT and legal connections are examined in relation to digital transformation, workforce analytics, HR systems, employment law compliance, and data protection obligations in regulated industries such as financial services.

Throughout, the video distinguishes the business partner role from traditional HR generalist work by contrasting its focus on strategic workforce planning, organisational design, change management, and talent development with older activity-based measures of HR performance. The contrast between horizontal integration — connections across business and operational functions — and vertical alignment with corporate strategy is made explicit, framing both as necessary for people practice to support the wider organisational strategies that AC 3.2 requires candidates to analyse.
