What Is an Acquired Solution?

(Chapter 71 of Systems Development Lifecycle (SDLC) Best Practices)

Executive Summary: Chapter Overview

IF4IT

The Bottom Line

Acquisition changes the allocation of work and control, but the enterprise remains accountable for the complete configured, integrated, operated, and retired Solution.

Core Concepts

Concept	Definition & Strategic Role
Governing Principle	Supplier ownership of a Product does not transfer enterprise accountability for suitability, configuration, integration, data use, acceptance, operation, renewal, exit, or retirement.
Lifecycle Accountability	Enduring ownership and Release-specific coordination remain explicit.
Evidence	Claims and decisions are supported by attributable, current, relevant, and sufficient evidence.
Risk-Based Tailoring	Depth changes with context; minimum outcomes and accountability remain.

Quick Q&A

Question: What makes a Solution Acquired?

Answer: The enterprise obtains a pre-existing Product, Service, platform, SaaS capability, license, or externally packaged technology and configures or integrates it for use rather than creating the core capability itself.

Question: Does acquisition remove Design and testing responsibilities?

Answer: No. The enterprise must still Design its use and integration, validate fit, configure controls, test the implemented context, accept outcomes, prepare operations, and govern suppliers.

Question: What evidence is especially important for an Acquired Solution?

Answer: Supplier due diligence, contractual obligations, Product and version information, configuration, integration, data, assurance reports, acceptance results, service commitments, portability, and exit evidence are central.

Defines Acquired Solutions and the enterprise responsibilities that remain when a supplier controls the core Product, Service, platform, or technology.

Governing Principle

Supplier ownership of a Product does not transfer enterprise accountability for suitability, configuration, integration, data use, acceptance, operation, renewal, exit, or retirement.

Required Lifecycle Treatment

Area	Required treatment
Scope	Includes commercial software, SaaS, cloud Services, managed Services, hardware, externally provided platforms, and other supplier-controlled capabilities.
Due diligence	Evaluate Product fit, supplier viability, evidence, risks, support, continuity, data use, and exit before commitment.
Contract	Translate lifecycle requirements into enforceable obligations, evidence, rights, remedies, notifications, and transition support.
Acceptance	Treat supplier release or implementation completion as input to enterprise V&V and authorization, not as automatic acceptance.
Operations	Monitor supplier changes, support status, incidents, vulnerabilities, renewals, and eventual replacement or exit.

Application Through the SDLC

Apply this discipline continuously from Intake through Retirement, translating the governing principle into testable requirements during Design and Build, generating decision-ready evidence through integration and acceptance testing, verifying the authorized state in Production and Operations, and closing remaining obligations at Retirement.

Governance and Evidence

Establish named ownership — Solution, Release, discipline, evidence, and Risk — proportionate to the work’s actual criticality and reversibility. Keep Risks, exceptions, and Technical Debt visible in authoritative systems, not buried in narrative updates. Generative AI may assist with analysis and drafting, but accountable decisions remain with named human authorities.

Common Antipatterns

Enterprises should avoid treating acquisition as a one-time purchase decision rather than a continuing relationship. The obligations of an Acquired Solution — configuration, monitoring, renewal, eventual exit — continue for the Product’s entire operational life; treating acquisition as complete once the purchase or initial implementation is done leaves these continuing obligations without an owner.

Antipattern	Why it fails
Treating acquisition as a one-time purchase decision rather than a continuing relationship	The obligations of an Acquired Solution continue for its entire operational life; treating acquisition as complete once purchased leaves configuration, monitoring, and renewal obligations without an owner.

Use Application Portfolio Management (APM) Best Practices and the Applications Inventory and Attributes to govern ownership, sourcing posture, lifecycle status, dependencies, and enterprise acceptance for custom-built and acquired solutions. Use Technology Portfolio Management (TPM) Best Practices, the Software Technologies Inventory and Attributes, and IT Operating Environments Best Practices to connect the decisions and responsibilities addressed in this chapter to governed technology choices, platform lifecycle, and environment controls.

Apply Release Management guidance together with IT Operating Environments Best Practices and Agile, Waterfall, or Hybrid: An IF4IT Framework for Choosing Delivery Methodology to keep Release scope, environment progression, deployment evidence, cutover, rollback, and closure properly governed.
