SAP Fit-Gap Analysis

This skill enforces evidence-based classification of every business requirement against SAP standard capability so that no gap is accepted without a resolution strategy, no fit is assumed without proof, and no custom development is committed without assessing clean core impact.

Iron Laws

1. NEVER CLASSIFY AS FIT WITHOUT PROVING STANDARD COVERS IT. "SAP probably handles this" is not a Fit classification. A Fit requires a named standard transaction, configuration path, or Best Practice process that demonstrably covers the requirement without modification.
2. NEVER ACCEPT A GAP WITHOUT A RESOLUTION STRATEGY. Every gap — whether configuration, development, process, or partial — must carry an explicit resolution: configure, extend (BAdI/BTP), workaround, or accept. An unresolved gap is a project risk, not a classification.
3. ALWAYS ASSESS CLEAN CORE IMPACT. Every Gap-Dev classification must be evaluated against SAP's clean core principles. Custom code inside the core (Z-programs, modifications) must be challenged. Side-by-side BTP extensions are preferred.
4. NEVER ESTIMATE GAP EFFORT WITHOUT A TECHNICAL APPROACH. A gap effort estimate without a named technical approach (configuration path, BAdI, BTP service, interface) is a guess. Do not produce numbers without first defining how the gap will be resolved.
5. INVOLVE THE PROCESS OWNER IN EVERY CLASSIFICATION. Business requirements classified without process owner confirmation are consultant assumptions. Classifications must be reviewed and signed off by the accountable business stakeholder before the matrix is baselined.

Rationalization Table

Agent Will Try To...	Why It Seems Reasonable	Why It Fails	Counter
Classify as Fit based on module familiarity	"We've done SD before — standard order-to-cash covers this"	Requirements vary by client. Client-specific pricing rules, approval workflows, or output formats routinely break assumed Fits.	Iron Law 1: Name the transaction or config path. If you cannot, it is not a Fit.
Leave a gap without resolution strategy	"We'll decide how to resolve it in Realize"	Unresolved gaps accumulate. By Realize, the backlog is so large that the resolution strategy defaults to custom development without proper evaluation.	Iron Law 2: Every gap row must have a resolution column populated at classification time.
Skip clean core assessment for Gap-Dev	"The client wants the custom report — just estimate it"	Custom code inside the core creates technical debt, blocks upgrades, and violates SAP's cloud roadmap. A side-by-side BTP extension may achieve the same result with zero core impact.	Iron Law 3: Every Gap-Dev must include a clean core impact rating (None / Low / Medium / High) and a justification.
Estimate effort before technical approach is defined	"The functional consultant can size it at a high level"	Without a technical approach, effort estimates have no basis. A BAdI-based extension might take 3 days; a full RAP object might take 15. The approach drives the number.	Iron Law 4: Technical approach column must be populated before the effort column.
Use only IT stakeholders for classification	"The business is too busy for workshops"	IT stakeholders may not know the actual business requirement. Process owners routinely override IT classifications in UAT. Surface the disagreement now.	Iron Law 5: Document the process owner who confirmed each classification. If unavailable, flag it as provisional.
Classify every variance as a gap	"If it requires configuration, it must be a gap"	Standard SAP configuration is not a gap — it is the mechanism for delivering Fit. Misclassifying configuration as a gap inflates gap counts and creates false urgency for custom development.	Classification rules: Gap-Config = achievable via standard configuration. Only Gap-Dev and Gap-Process represent true divergence from standard.
Ignore partial fits	"It's mostly covered — call it a Fit"	Partial fits carry hidden scope. The uncovered portion becomes a late-stage gap that is more expensive to resolve once design is locked.	Classification rules: Partial fit = its own category. Document what is covered and what is not.

Red Flags

Watch for these phrases in your own reasoning — each one signals you are about to violate an Iron Law:

• "SAP standard handles this..." → Name the transaction or config path. If you cannot, stop.
• "We can decide on the resolution later..." → Every gap needs a resolution strategy now.
• "The client wants custom code for this..." → Have you assessed the clean core impact? Stop.
• "Let me estimate this gap at roughly X days..." → What is the technical approach? Define it first.
• "The IT team confirmed this as a Fit..." → Did the process owner confirm it? Flag as provisional until they do.
• "This is a minor gap, we can absorb it..." → Minor gaps have effort and risk. Classify and size it.
• "We'll just build a workaround..." → Workarounds must be documented with effort, owner, and risk rating.
• "This gap is the same as the last project..." → Requirements vary by client. Validate it here.

Hard Gates

DO NOT produce a fit-gap matrix until ALL of the following exist: 1. Full list of in-scope business requirements, numbered and traceable to a source (workshop, RFP, process document) 2. SAP Best Practice process scope defined (which Scope Items are activated in the system) 3. Classification criteria agreed with the project team (Fit / Gap-Config / Gap-Dev / Gap-Process / Partial) 4. Process owner identified for every requirement area 5. Technical approach defined for every Gap-Dev before effort is estimated 6. Clean core impact assessed for every Gap-Dev classification

Checklist

Step 1: Gather and Number All Requirements

Before any classification begins, compile the complete requirement set:

• Source documents: Workshop outputs, RFP, AS-IS process documentation, stakeholder interviews
• Numbering convention: Assign a unique ID to every requirement (e.g. FGA-SD-001)
• Traceability: Record the source document and page/section for each requirement
• Scope boundary: Confirm which requirements are in-scope vs. out-of-scope for this project

Evidence: Numbered requirements list with source traceability and scope boundary confirmed. Gate: No classification begins until all in-scope requirements are identified and numbered.

Step 2: Define SAP Standard Baseline

Establish what "standard" means for this project:

• SAP Best Practice Scope Items: Which scope items are activated? Which are the baseline processes?
• SAP Release: S/4HANA version — on-premise, RISE, or Public Cloud (determines available configuration options)
• Country version: Localization requirements (tax, legal, payments) that are standard vs. country-specific
• Industry solution: Any SAP industry add-ons that extend the standard baseline

Evidence: Scope item list with SAP release and country version documented. Gate: No requirement is classified as Fit against functionality that is not confirmed to be in scope for activation.

Step 3: Classify Every Requirement

Apply the five-category classification to every numbered requirement:

Classification Definitions:

Classification	Definition	Resolution Path
Fit	Requirement is fully met by SAP standard without any configuration or development beyond standard activation	No action required
Gap-Config	Requirement is met by SAP standard through configuration (org structure, settings, output types, pricing, etc.)	Configure in Realize
Gap-Dev	Requirement cannot be met by standard configuration — requires development (BAdI, extension, report, interface, BTP app)	Develop — assess clean core impact
Gap-Process	SAP standard delivers the outcome but via a different process than the client currently uses — no system change needed, business process change required	Process change management
Partial	Requirement is partially met by standard — some elements are Fit or Gap-Config, other elements require development or process change	Decompose into sub-requirements and classify each

For every Gap-Dev, additionally record:

• Technical Approach: BAdI / BTP Side-by-Side / RAP Extension / CDS View / Interface / Report / Modification (flag modifications as high risk)
• Clean Core Impact: None / Low / Medium / High
• Clean Core Justification: Why this approach was selected over a cleaner alternative

Evidence: Every requirement has a classification, and every Gap-Dev has a technical approach and clean core impact rating. Gate: No Gap-Dev row has an empty technical approach column.

Step 4: Define Resolution Strategy Per Gap

For every non-Fit classification, define how the gap will be resolved:

Resolution Options:

Resolution	Definition	When to Use
Configure	Use standard SAP configuration to meet the requirement	Gap-Config
Extend	Use SAP-endorsed extension points (BAdI, BTP, RAP) — no core modification	Gap-Dev where clean core can be maintained
Workaround	Use a different SAP process or combination of standard functions to meet the business outcome without development	Gap-Process or low-priority Gap-Dev
Accept	Business accepts that SAP will not meet this requirement as stated — either drop the requirement or re-define it	Low-priority requirements where cost of resolution exceeds value

Evidence: Every gap has a named resolution strategy with justification. Gate: "TBD" is not a valid resolution strategy. Any requirement with an unresolved strategy is flagged as a project risk.

Step 5: Estimate Effort Per Gap

Size the resolution effort for every Gap-Config and Gap-Dev:

• Gap-Config: Estimate configuration days (Design + Configure + Unit Test)
• Gap-Dev: Estimate development days by phase (Design, Develop, Unit Test, Integration Test) — use three-point (O/R/P)
• Gap-Process: Estimate change management effort (process documentation, training, communication)
• Priority: Assign each gap a priority (Must Have / Should Have / Could Have) — this drives sequencing in Realize

Evidence: Effort estimate per gap with three-point values for Gap-Dev items. Gate: No single-point estimates for Gap-Dev. Complexity and technical approach must justify the estimate.

Step 6: Assess Clean Core Risk Portfolio

Review all Gap-Dev classifications as a portfolio:

• Modification count: How many requirements require core modifications (highest risk)?
• BTP extension count: How many can be resolved via side-by-side BTP extensions?
• Upgrade risk: Which custom developments will be affected by future SAP upgrades?
• Clean core score: Calculate the ratio of clean extensions to total Gap-Dev items

Evidence: Clean core portfolio summary with modification count, BTP extension count, and upgrade risk items flagged. Gate: Any core modification must be escalated to the solution architect and client IT lead before classification is baselined.

Step 7: Review and Sign Off with Process Owners

Conduct fit-gap review workshops with business process owners:

• Walk through each requirement classification with the accountable process owner
• Record agreement or challenge for every classification
• Update classifications based on process owner input
• Obtain sign-off on the baselined fit-gap matrix before Realize begins

Evidence: Sign-off record with process owner name, date, and any classification changes made. Gate: No fit-gap matrix is baselined without process owner review documented.
