Driving IT change…
Enterprise Technology rarely exists without a business purpose. An IT department’s aim is to make it easier for their organisation to deliver relevant, efficient and quality services to its end customers.
CoStratify has a strong technical and service delivery background but we know it’s difficult to make actionable recommendations without first understanding how you use IT. This is why our unique approach gives us just enough information about your organisation to quickly make relevant observations and recommendations. We specialise in an approach that is a simplified version of Enterprise Architecture that not only covers technical change but takes into account your IT service and most importantly the benefits to your organisation IT must bring.
It’s an approach that has been refined over years of working across multiple customers in multiple sectors including local government, housing, healthcare and finance. We use an experienced network of associates to provide foresight and thought leadership, with each Enterprise Architect or consultant having over 15 years experience in delivering IT change programmes and IT strategies.
We know you will gain value from our approach and our pragmatic mindset. Call us today and arrange a meeting to discuss how our approach can best help you.

Our Mission

Our mission is to ensure we help customers gain the most value from their IT. Our goal is to help you choose the right approach, technology and services in a deliberately strategic way. We believe in continuously helping to inform you of these choices as your organisation navigates challenges and constraints.
We are always on your side and we offer advice that we believe is best for you, based on facts and strategic thought. We make recommendations and stick by our decisions, helping you when you need a partner most but not interfering when you don’t.
Our Enterprise Architecture approach is about consistency, transparency and continuity, enabling you to uplift your IT services and align them with the business whilst keeping down costs and being efficient in delivery.
