How to Read a Dynamics 365 Partner's Case Studies Like a Due Diligence Analyst

You're evaluating Dynamics 365 partners for a six-figure ERP implementation. You've read the capabilities decks. You've sat through the demos. Now you're looking at case studies — but are you reading them correctly? Most buyers skim case studies for industry relevance and move on. That's a mistake. Our analysis of 2,419 case studies across the Dynamics 365 ecosystem reveals that how a partner presents their past work contains specific, measurable signals that predict your likely experience.

This isn't a guide to what case studies say. It's a guide to what they reveal — the patterns, gaps, and details that separate partners who document genuinely strong delivery from those using case studies as marketing collateral.

Key Takeaways

• Partners whose case studies cover a single industry average 4.48 client satisfaction with just 9.5% negative reviews. Those covering 4+ industries average 4.33 with 14.3% negative reviews. In case study portfolios, focus predicts quality — treat scattered industry coverage as a yellow flag.
• Written case studies correlate with better client outcomes (4.37 avg) than video-only testimonials (3.99 avg). Video testimonials feel more authentic but are harder to evaluate critically and often lack the specific detail that separates marketing from evidence.
• Partners with quantified metrics in their case studies ("reduced close time by 40%") average 4.39 client satisfaction versus 4.31 for those with vague outcomes ("improved efficiency"). Demand specific numbers — they signal a culture of measurement.
• Only 8.6% of Dynamics 365 case studies address migration projects despite migrations being among the most complex engagement types. If you need a migration, a partner with documented migration experience is in a rare and valuable minority.
• The presence of any published case studies at all is a positive signal — partners with case studies average 4.36 versus 4.29 for those without. But the details within those case studies matter more than their existence. Use this guide to read them like a due diligence analyst, not a marketing audience.

Signal #1: Industry Concentration vs. Industry Scatter

The first thing most buyers check is whether a partner has case studies in their industry. That's reasonable — but the deeper signal is in how concentrated or scattered the partner's case study portfolio is.

Case Study Diversity	Partners	Avg Client Rating	Negative Review Rate
Single industry focus	7	4.48	9.5%
2–3 industries	42	4.43	11.3%
4+ industries	50	4.33	14.3%

Partners with case studies concentrated in a single industry have the highest client satisfaction at 4.48 stars and the lowest negative review rate at 9.5%. As industry scatter increases, satisfaction drops monotonically. Partners covering 4+ industries average 4.33 — still respectable, but with a 14.3% negative rate that's 50% higher than the focused group.

This mirrors the specialization sweet spot we found in product portfolios. Depth beats breadth. When a partner's case studies span Manufacturing, Healthcare, Retail, Financial Services, and Government, ask yourself: is this a firm with genuine multi-vertical expertise, or one that takes any project it can win? The data suggests the latter is more common.

What to do: Count the distinct industries across a partner's case study portfolio. If it's 1–3, that's a positive signal. If it's 5+, probe deeper on their specific experience in your vertical during the evaluation process.

Signal #2: Written Case Studies vs. Video Testimonials

The format of a partner's case studies matters more than you'd think. Of the 2,419 case studies we analyzed, 90.5% were written (HTML), 9.3% were video transcripts, and the remainder were PDFs.

Written-only partners average a 4.37 client rating. Video-only partners average 3.99. Partners with both formats come in at 4.31.

Why would video correlate with worse outcomes? It's counterintuitive — video testimonials feel more authentic and personal. But written case studies require a partner to articulate specific project details, challenges, solutions, and results in a structured format that's easy for buyers to evaluate critically. Video testimonials are often short, emotionally driven, and light on specifics. They're marketing tools. Written case studies, when done well, are evidence.

What to do: Don't dismiss video testimonials, but don't let them substitute for detailed written case studies. A partner who has both is investing more heavily in client storytelling — even if the satisfaction data for mixed-format partners (4.31) doesn't significantly outperform written-only (4.37).

Signal #3: Quantified Results vs. Vague Outcomes

This is the single most actionable signal in any Dynamics 365 case study. Open the case study and look at the outcomes section. Do you see specific numbers — "30% reduction in order processing time," "cut monthly close from 12 days to 4," "$240K annual savings in inventory carrying costs"? Or do you see generic statements — "improved operational efficiency," "enhanced customer satisfaction," "streamlined processes"?

In our dataset, the phrase "enhanced operational efficiency" appears 55 times. "Improved operational efficiency" appears 53 times. "Increased operational efficiency" appears 51 times. These three near-identical vague outcomes account for 159 entries — and they tell you absolutely nothing about what the partner actually delivered.

Partners with quantified metrics average 4.39 client satisfaction. Partners with vague outcomes average 4.31. The gap is modest in star rating but signals something important about organizational culture: a partner who measures results precisely is more likely to manage projects precisely.

What to do: For any partner on your shortlist, open their case studies and count how many include specific, quantified results. If none do, ask the partner directly: "What specific metrics improved for this client, and by how much?" If they can't answer, the case study was written by marketing, not delivery.

Signal #4: Project Type Relevance

78% of all published case studies cover new implementations. Only 8.6% address migrations, 7% cover optimization, 3.8% address support, and 2.5% cover integrations.

This creates a critical evaluation gap for buyers who need something other than a greenfield implementation. If you're migrating from Dynamics NAV or GP to Business Central, a partner who has published migration-specific case studies is demonstrating experience in a project type that only 8.6% of partners bother to document.

The satisfaction data supports seeking project-type matches:

• Support-focused case studies: 4.62 avg rating (partners confident enough to document ongoing relationships)
• Migration-focused: 4.42 (complex work that requires specialized experience)
• Implementation-focused: 4.35 (the standard, broadest category)
• Integration-focused: 4.15 (technically demanding, higher risk of complications)
• Optimization-focused: 4.11 (often involves fixing problems from prior implementations)

What to do: Match your project type to the partner's case study portfolio. A migration project deserves a partner with documented migration experience. An integration project deserves a partner who has published integration case studies. Don't accept implementation-only case studies as proof of migration capability — they're different skill sets.

Signal #5: Customer Size Alignment

57.7% of case studies feature mid-market customers. Enterprise accounts for 30.4%, and SMB just 4.3%. If you're a small business, finding a partner with SMB-relevant case studies puts you in rare territory — and that specificity is worth prioritizing.

Customer size alignment matters because the implementation dynamics are fundamentally different across segments. A mid-market Business Central deployment for a 200-person manufacturer has different scope, timeline, and risk characteristics than an enterprise F&O rollout for a 5,000-person multinational. A partner's case study portfolio should reflect experience at your scale.

What to do: Check whether the customers in a partner's case studies are similar in size to your organization. A partner with 10 mid-market manufacturing case studies is a stronger fit for your mid-market manufacturing ERP project than a partner with 3 enterprise Financial Services case studies — regardless of their certification level or headcount.

Signal #6: Named Customers vs. Anonymous References

Some partners name their customers openly: "How Contoso Manufacturing Reduced Production Costs by 22% with Business Central." Others anonymize: "A Leading Manufacturer Improves Efficiency with Our ERP Solution."

The difference signals client relationship quality. A partner whose clients agree to be named publicly is demonstrating something important: the client relationship was strong enough that the customer is willing to serve as a reference. Anonymous case studies might reflect legitimate confidentiality requirements — or they might reflect clients who wouldn't endorse the partner if asked.

In our dataset, partners who name most of their customers average a 4.38 client rating with a 12.7% negative review rate. While we couldn't establish a meaningful comparison group (nearly all partners with 2+ case studies name most customers), the practice itself is worth noting as a baseline expectation.

What to do: If a partner's case studies are all anonymous, ask why. Legitimate industries (healthcare, government) often require anonymity. But a consulting firm with 5 anonymous Manufacturing case studies should be able to provide at least one named reference.

Signal #7: Recency and Platform Currency

Products evolve. A case study featuring Microsoft Dynamics NAV was written for a product that was superseded by Business Central. NAV still appears in 71 case studies across our dataset — and in some cases, it's the most recent case study a partner has published.

A partner whose latest case study references NAV without a migration context hasn't updated their content in years. That's a signal: either they've stopped winning new projects worth documenting, or their marketing function is dormant. Both are concerning.

Look for case studies that reference current platform features: Business Central's AI capabilities, Power Platform integration, cloud-native deployment, Copilot features, or recent wave updates. Currency in content reflects currency in expertise.

What to do: Check the dates and product references in a partner's case studies. If the most recent one is more than 18 months old or references discontinued products, factor that into your evaluation. A partner actively publishing current case studies is a partner actively winning and delivering projects.

Putting It All Together: The Case Study Due Diligence Checklist

When evaluating a Dynamics 365 implementation partner, use this framework to read their case studies critically:

1. Do they have case studies at all? Only 14.8% of partners publish them. Presence is a positive baseline signal.
2. Are the industries focused (1–3) or scattered (4+)? Focus correlates with better outcomes.
3. Are results quantified or vague? Specific numbers signal a measurement culture.
4. Do the project types match your needs? Don't accept implementation case studies as proof of migration capability.
5. Are the customers your size? Mid-market dominates; if you're SMB or enterprise, look for size-aligned evidence.
6. Are customers named or anonymous? Named customers suggest stronger client relationships.
7. Are the case studies recent and referencing current products? Stale content suggests stale expertise.

No single signal is definitive. A partner can have excellent delivery with no published case studies — especially smaller firms that prioritize client work over marketing. But when case studies exist, they contain more information than most buyers extract. Read them like an analyst, not a prospect, and you'll make a better-informed partner selection decision.

Frequently Asked Questions

How important are case studies when evaluating a Dynamics 365 partner?

Case studies are a meaningful but not definitive signal. Partners who publish Dynamics 365 case studies average a 4.36 client rating versus 4.29 for those who don't. More importantly, the details within case studies — quantified metrics, industry focus, project type relevance — provide specific evaluation criteria that capabilities decks and demos can't match.

Should I avoid a Dynamics 365 partner that has no case studies?

Not necessarily. Only 14.8% of partners publish case studies, and many excellent smaller firms don't invest in content marketing. However, if a partner has more than 100 employees and no published case studies, that's worth questioning — either they haven't had projects worth documenting, or their marketing maturity is low. Both are relevant data points.

Are video testimonials as useful as written case studies?

Our data shows written case studies correlate with higher client satisfaction (4.37 avg) than video-only testimonials (3.99). Written case studies force partners to articulate specific details — challenges, solutions, and quantified results — in a format you can evaluate critically. Video testimonials tend to be shorter and more emotional, which makes them persuasive but less informative for due diligence purposes.

What is the most important thing to look for in a Dynamics 365 case study?

Quantified results. Partners who include specific metrics ("30% reduction in processing time") average 4.39 client satisfaction versus 4.31 for those with vague outcomes ("improved efficiency"). Quantification signals a delivery culture that measures outcomes — which is the same culture most likely to manage your project rigorously.

How many case studies should a good Dynamics 365 partner have?

Quality matters more than quantity. Partners with focused case study portfolios (1–3 industries) outperform those with scattered coverage (4+ industries) by 0.15 stars and a nearly 5-point gap in negative review rates. Three well-crafted, industry-specific case studies with quantified results are more valuable than ten generic ones covering every vertical imaginable.

Do case studies predict implementation success for Dynamics 365?

Case studies are one predictor among several. They correlate with modestly higher client satisfaction and signal organizational maturity, but they don't guarantee success. Combine case study analysis with client review analysis, direct reference checks, and technical conversations with the delivery team for a complete evaluation picture.
