Setup or migration service available
How the setup or migration service works
Our pioneering, and award winning, work in cloud adoption has enabled a range of clients, including those with sensitive data and business processes to protect, to successfully exploit public cloud services from the major providers including AWS, Google and Microsoft. PA offers a full lifecycle of services to support your cloud adoption journey which are tailored to your situation and focused on achieving your outcomes.

We work closely with you to develop your overall cloud and hosting strategy through to defining and implementing the required target operating model to successfully exploit cloud including establishing new capabilities and ways of working (e.g. DevOps and Agile). PA recognises the importance of resilience and cyber security across cloud architectures and our Digital Trust team, who have worked with the most sensitive areas of UK government, bring a range of security testing and assurance capabilities that cover every aspect of enterprise cloud security. Our Migration and Transformation capabilities assess existing applications to identify and execute the preferred cloud migration approach (“lift and shift” or re-architect) supported by a strong business case.

Our Digital Operations team brings the new blend of capabilities (people, processes and tools) required to successfully manage and optimise your cloud solutions.

Quality assurance and performance testing

Quality assurance and performance testing service
How the quality assurance and performance testing works
PA is committed to ensuring that it always delivers the highest levels of quality to its clients. PA’s remuneration policy is based heavily on performance for clients, and is validated by specific feedback channels from clients to PA. The primary mechanism for capturing our clients’ views is through our Client Satisfaction Survey process, in which we seek feedback on PA’s performance on specific assignments. PA takes this process seriously and thus the review is normally carried out by an independent member of PA’s senior management group in a face-to-face meeting with the client. The Partner in Charge of the assignment will hold an active leadership role with ultimate responsibility for the delivery of all our work to meet client’s needs and in a manner that meets the client's culture and values. PA holds an IS09000 certification.
