Paperback. Condition: new. Paperback. Product-market fit is often discussed as a feeling. This book turns it into a disciplined, measurable practice. It shows founders, product leaders, marketers, and analysts how to define fit in operational terms, connect it to real customer behavior, and track the signals that matter before growth becomes expensive guesswork.Rather than relying on anecdotes or vanity metrics, the book builds a clear framework around validation, adoption, retention, and growth. Readers learn how to choose the right unit of analysis, create a useful metric map, and set up dashboards that answer specific business questions. The approach is practical, with an emphasis on measurement design, data quality, and consistent ownership.What the book coversCustomer validation metrics that show actual demand, from intent and willingness to pay to activation readiness.Adoption analysis that tracks time-to-value, feature usage, workflow coverage, and early drop-off points.Retention measurement using cohorts, windows, and outcome-based definitions for users, accounts, and revenue.Growth signals that separate true market pull from raw marketing volume, including source quality, expansion, referrals, and revenue behavior.Experiment design to test assumptions with clear hypotheses, success criteria, and guardrails.Instrumentation and data governance so metrics are reliable, consistent, and trustworthy.Segment analysis to identify where fit exists by persona, use case, channel, company size, and maturity.Pricing and billing metrics that reveal whether the product, packaging, and onboarding journey match customer value.The book also provides practical playbooks for reading conflicting signals, such as strong validation with weak adoption or stable retention with sluggish growth. These sections help teams diagnose what is happening, why it matters, and what to test next.Ideal for early-stage teams and scaling companies alike, this guide helps organizations build a repeatable process for knowing when the market is responding, where it is responding, and how to act on that evidence with confidence.

Paperback. Condition: new. Paperback. Quantum computers aren't here to ruin your week. yet. But the cryptography protecting today's internet? A lot of it comes with an expiration date. If you build or run modern systems, post-quantum cryptography (PQC) isn't a "future problem." It's a migration problem. And migrations have a special talent for breaking production at 2:00 a.m. The Quantum-Ready Architect is your practical, architecture-first guide to upgrading real systems using hybrid cryptography (classical + PQC)-without panic, theory overload, or "just re-encrypt everything" nonsense.This is not a math textbook.This is a "ship it safely" playbook.If you're responsible for any of this.TLS and mTLS across load balancers, gateways, proxies, and service meshesPKI, certificates, trust stores, rotations, and renewalsVPNs, remote access, and Zero Trust networkingCode signing, CI/CD pipelines, artifacts, and firmware updatesLong-term data security (backups, archives, compliance retention).then you're in the right place. What you'll actually learn (and implement)How to find crypto hiding in your stack with a Crypto Bill of Materials (CBOM)How to prioritize migration using risk + data shelf-life scoringProven hybrid deployment patterns you can roll out incrementallyHow to modernize PKI without triggering a certificate apocalypseHow to upgrade TLS/mTLS and QUIC with canary releases + rollback plansHow to protect data at rest (KMS/HSM workflows, rewrap vs re-encrypt)How to keep the software supply chain secure with transitional signing strategiesHow to test interoperability, measure performance, monitor failures, and stay sane Who this book is for Architects, security engineers, platform engineers, SREs, and technical leaders who want to go from: "We should be quantum-ready someday" to "We have a real plan, a rollout path, and working hybrid crypto in production." Who this book is NOT for If you want deep cryptographic proofs and heavy math-there are excellent academic texts for that. This book is for people who need to make systems survive the future and stay online today.Quantum is coming.Your legacy systems are not ready.Let's fix that-one safe rollout at a time.Start now. Migrate smart. Stay ahead. This item is printed on demand. Shipping may be from multiple locations in the US or from the UK, depending on stock availability.…
