Harrison’s comprehensive framework outlines the process for organisations to smoothly integrate Cloud Services with existing legacy and traditional IT services, ensuring the delivery of reliable and efficient business-facing solutions. The Cloud enables quick deployment, adaptability, and agility, but the transition strategy must carefully consider the balance between speed and stability to maintain uninterrupted service for the business.

Harrison’s overall framework for the transition of IT services is detailed below.

our approach

Ensure clarity regarding the roles and responsibilities:
One of the main obstacles during the shift to Cloud services is guaranteeing the
clarity of the Cloud service’s scope and the well-defined interface between the Clo
Provider and the SIAM function in the contract. It is crucial to ensure that all parties
comprehend and fulfill their transition responsibilities, which should be integrated in
the comprehensive plan. Testing this with all involved parties at the beginning of the
transition planning process is essential to identify and eliminate any
misunderstandings

Incorporate the transition approach within the contractual
agreement:
Contract negotiations often overlook the transition responsibilities, which can lead to
delays and disruptions in IT transitions. The lack of clarity regarding each party’s
responsibilities is a common cause of confusion. Outgoing suppliers typically adhere
strictly to what is dened in the contract, and cloud-based services offer limited
exibility. Hence, it is crucial to identify any gaps in transition responsibility early on
and negotiate with the supply chain to establish a practical remediation approach.
This may involve incorporating risk mitigation clauses into new contracts and
encouraging both the SIAM function and incoming tower suppliers to assume
additional transition responsibilities

Create and assess options for migrating to the cloud:
Engaging stakeholders at an early stage throughout the organisation, including ICT
and the supply chain, is crucial to identifying and assessing all possible transition
strategies. Our collaboration will focus on creating practical transition plans that bring
immediate value to the business, safeguarding current services, and adhering to
contractual obligations. Additionally, we will guarantee a thorough evaluation of
transition alternatives to support the necessary tough choices in the future stages of
the process.

Verify that the service performance baseline is clear:
Ensuring a smooth transition involves safeguarding service levels and minimising
business interruptions. It is crucial to have a solid understanding of the current
service performance baseline, supported by concrete evidence rather than anecdotal
or limited historical data. Simply collecting monthly service reports from existing
suppliers may not suce, as service boundaries may differ and performance data for
the service being replaced could be intertwined with other KPIs, making it challenging
to pinpoint.
To tackle this issue, our team will collaborate closely with you to ensure that the
signince of the performance data is comprehended and given the appropriate
priority in the Transition Plan. Additionally, we will engage with suppliers to accurately
map the service data from both incoming and outgoing services, enabling us to make
a meaningful comparison and establish suitable service levels for the new service.

Conduct a thorough assessment of the supplier’s due diligence
procedures:
Based on our expertise, there is no superior method to minimise the risks associated
with transitioning a business-critical IT service than ensuring that the incoming
supplier can clearly articulate their transition approach, the extent of the service they
will undertake, and the performance metrics they will deliver once they assume
responsibility. By formalising their approach in a document that is then collaboratively
developed, reviewed, and red, the supplier demonstrates their commitment to due
diligence and thoroughly examines the intricacies of the service they will be
accountable for. This process also presents an opportunity to foster collaborative
work with the supplier prior to the service cut-over, allowing relationships to rish
and work methodologies to evolve in a relatively low-risk environment.
