Engagement Models and Global Delivery Approaches

Why Delivery Model Shapes Cost More Than Engagement Model Alone

An institution assuming that engagement model alone determines an implementation's total cost is missing the classification that actually shapes cost more directly.

Within the Aladdin implementation market, onshore, offshore, nearshore and hybrid global delivery choices affect total implementation cost independently of whether the engagement itself is structured as advisory-led, implementation-led or outcome-based.

This page describes six engagement models and four delivery models strictly as market categories, and it makes no claim about the delivery quality or comparative performance of any named provider under any specific model.

Two institutions signing an outwardly similar implementation-led contract can end up with very different total costs purely because one specified onshore delivery throughout and the other allowed a hybrid onshore and offshore delivery structure.

Institutions negotiating a new engagement increasingly separate the engagement model discussion from the delivery model discussion explicitly, rather than treating delivery location as a minor implementation detail settled after the commercial terms are agreed.

Institutions that negotiate delivery model terms separately from engagement model terms typically achieve more predictable total cost outcomes, since bundling both decisions into a single negotiation can obscure which factor is actually driving a given price difference between competing proposals.

A clear separation of these two decisions also makes it easier for an institution to benchmark competing proposals on a like-for-like basis, since two providers offering the same engagement model can still differ substantially once delivery model is factored in.

Institutions that have previously run an implementation without separating these two decisions often cite that experience directly when structuring their next request for proposal, building in explicit delivery model questions from the outset.

Advisory-Led and Implementation-Led Engagement

Advisory-led engagement centres on strategic guidance, typically covering the strategy, vendor selection and target operating model design stages described on the services page, without the provider taking direct responsibility for platform configuration.

Implementation-led engagement shifts the provider into direct responsibility for building and deploying the platform configuration itself, typically following on from an advisory-led engagement once design decisions are finalised.

Institutions frequently split a single transformation programme across both models, engaging one firm for advisory-led design work and a different, often more technically specialised, firm for implementation-led delivery.

This split-engagement approach can introduce coordination overhead between the two providers, a factor institutions increasingly plan for explicitly in programme governance rather than treating the handover as a simple contract transition.

Institutions with limited internal transformation experience often start with a purely advisory-led engagement to build internal confidence in the target operating model before committing to a larger implementation-led contract.

The transition point between advisory-led and implementation-led engagement is a natural moment for an institution to revisit its provider selection, since some advisory specialists deliberately do not offer implementation-led services at all.

Institutions that skip a formal advisory-led phase and move directly into an implementation-led contract sometimes discover mid-programme that key operating model decisions were never fully agreed, a gap that a dedicated advisory phase is specifically designed to close.

Staff Augmentation and Outcome-Based Delivery

Staff augmentation places individual specialist practitioners inside an institution's own team structure, typically used when an institution wants to retain direct control over programme management while filling specific skill gaps.

Outcome-based delivery ties provider compensation to defined delivery milestones or business outcomes rather than time and materials, shifting more delivery risk onto the provider in exchange for typically higher contract value.

Institutions with strong internal programme management capability more often favour staff augmentation, while institutions preferring to transfer delivery risk more often favour outcome-based delivery.

Outcome-based contracts require an institution to define delivery milestones with unusual precision up front, since ambiguous milestone definitions are a common source of dispute once a programme is already underway.

Staff augmentation arrangements, by contrast, place the burden of coordinating multiple individually sourced specialists back onto the institution's own programme office, a trade-off institutions weigh against the greater direct control the model provides.

Hybrid arrangements combining staff augmentation for specialist roles with outcome-based delivery for a defined workstream are increasingly common on larger programmes, allowing an institution to match contracting structure to the specific risk profile of each workstream.

Institutions selecting staff augmentation still bear responsibility for defining the specific configuration and testing standards augmented staff should follow, since the model provides skilled individuals rather than a fully accountable delivery team.

Rate structures under staff augmentation are typically transparent and role-based, making it straightforward for an institution to compare providers on a like-for-like basis, whereas outcome-based pricing is harder to compare directly across competing proposals.

Institutions blending both models within one programme typically reserve outcome-based terms for the most clearly defined technical workstreams, keeping staff augmentation for roles requiring closer day-to-day direction.

Managed Services and Hybrid Delivery Engagement

Managed services engagement represents the most commercially distinct engagement model, structured as an ongoing relationship rather than a finite project.

Hybrid delivery engagement blends elements of two or more of the other five engagement models within a single contract, increasingly common on large, multi-year transformation programmes that span implementation and subsequent ongoing support.

The choice between these engagement models often depends on which delivery stage an institution has reached, since early-stage strategy work suits advisory-led engagement while later-stage optimisation work often suits managed services.

Institutions moving from a finite implementation-led contract into an ongoing managed services relationship frequently renegotiate pricing entirely, since the risk profile and staffing pattern of ongoing administration differ substantially from project-based delivery.

Hybrid delivery engagement is particularly common where an institution's transformation programme spans multiple platform modules being rolled out in separate phases, each potentially suited to a different engagement model.

Institutions transitioning into managed services frequently negotiate a defined transition period during which the incoming managed services team shadows the outgoing implementation team, reducing the risk of knowledge loss at the handover point.

Hybrid delivery engagement contracts typically specify which specific workstreams fall under which engagement model explicitly, rather than leaving the blend to be worked out informally once the programme is underway.

Service level agreements attached to a managed services contract typically cover platform availability, issue response time and periodic health check delivery, giving an institution a concrete basis for measuring ongoing provider performance.

Institutions renewing a managed services contract after its initial term frequently renegotiate service level terms based on actual platform usage patterns observed during the first contract period, rather than the assumptions used when the original agreement was signed.

Onshore, Offshore, Nearshore and Hybrid Global Delivery

Onshore delivery keeps implementation staff based in the same country or region as the client, typically commanding the highest rates but preferred for core investment operations work with the highest sensitivity.

Offshore delivery, most often based in established technology delivery hubs, lowers total cost of ownership considerably, particularly for data migration and testing work that is less dependent on close, real-time client interaction.

Nearshore delivery balances cost and proximity, commonly used by European and North American clients seeking lower rates than pure onshore delivery without the time zone separation of full offshore delivery.

Hybrid global delivery, blending onshore relationship management with offshore or nearshore execution, has become the dominant delivery model among the larger implementation providers competing for large institutional programmes.

Institutions selecting a delivery model increasingly weigh time zone overlap with their own operations team as heavily as headline rate differences, since limited overlap can slow issue resolution during critical stages like testing and go-live support.

Regulatory data residency requirements in certain jurisdictions can constrain which delivery model an institution can actually use for specific workstreams, particularly around data migration work involving sensitive client or position-level information.

Institutions increasingly request delivery model transparency from providers upfront, asking exactly which stages of the engagement will be delivered onshore versus offshore or nearshore, rather than accepting a general hybrid delivery label without further detail.

Providers offering hybrid global delivery typically publish an indicative split, such as the proportion of a programme expected to run onshore versus offshore, giving institutions an early basis for cost comparison before detailed staffing plans are finalised.
