Updated on 21 September 2026. What’s new: every Pega exam live today with its questions, time, pass mark and fee, replacing the old list built on CPSA Version 23.

Pega offers eight live certifications, each tied to a role: three System Architect levels (CPSA, CPSSA and CPLSA) for developers, plus Business Architect, Decisioning Consultant, Data Scientist, Robotics System Architect and Customer Service Developer. Every exam costs USD $190 and has 50 or 60 questions. Most beginners should start with the System Architect exam.

Pega (Pegasystems) builds a low-code platform for case management, workflow automation, customer decisioning and robotic automation. Banks, insurers, telecom providers and government agencies run large parts of their operations on it, and they need people who can prove they know how to build on it. A Pega certification is that proof. It is issued by Pega Academy and tested by Pearson VUE, and each one is tied to a specific product release, so a current credential shows your skills match the platform as it is used today.

This guide replaces our older article on four Pega certifications. Pega's line-up has grown and changed since then, so here you will find every exam that is live today, what each one costs, how the exams compare, which path to follow and how to prepare for your first attempt.

The way we communicate with business is changing, from online to offline. Organizations are going through fundamental change. At the heart of this transformation is the business architect.

Who is a Business Architect?

A Business Architect understands and contextualizes strategy for operational requirements, develops specific remainders such as business capability maps. And value streams to help connect the gap between strategy and execution, and assists streamline and rationalize the IT enablement process.

In addition to developing particular deliverables, views, and viewpoints, a business architect synergies and synthesizes the work of others drawing from methods such as strategy process management, development, systems analysis, business analysis, and operations.

However, in fact, in many large companies, the role of a business architect has devolved into an arm of IT and has run into uncertainty about the specific nature, deliverables, and intended outcomes from the position. The change has to do with a lot of factors, and none of which alone can resolve the status quo.

Updated on 19 September 2026. What’s new: CQE exam fees corrected to $450 for ASQ members, $550 for non-members and $350 for retakes.

To become a Certified Quality Engineer, you meet ASQ's experience requirement of eight years in quality engineering work (three in a decision-making role, with up to five years waived for a degree), apply to ASQ, study the seven areas of the CQE Body of Knowledge, pass the 175-question exam with a score of 550/750, and then recertify every three years. The five steps below walk through each one.

The ASQ Certified Quality Engineer (CQE) credential is one of the longest-standing certifications in the quality profession. It is awarded by the American Society for Quality (ASQ) and recognises engineers who can design quality systems, control products and processes, apply statistics to real production data and lead improvement work. Because the exam is demanding and the experience requirement is strict, employers read the letters CQE as proof of both knowledge and practice.

This guide is for quality engineers, quality assurance specialists, manufacturing and process engineers, and supplier quality professionals who want to know exactly what it takes to earn the credential. It covers the requirements, the fees, the exam format, every area of the Body of Knowledge, a preparation plan, the mistakes that cost candidates a pass, and how to keep the certification once you have it.

A retail replatform ran as strict Waterfall: nine months of requirements, one go-live date, a change board for every amendment. By month four the business had rethought checkout, the specification was frozen, and the team shipped the document rather than the product. The rework cost more than the original build. Waterfall was not the problem; it was the wrong fit. There is no best project management methodology, only the one that matches your scope, your rate of change and your governance.

That mismatch is the real question hiding behind “which methodology is best”. This guide maps eight approaches – Waterfall, Agile, Scrum, Kanban, Lean, Six Sigma, PRINCE2 and hybrid – and for each one explains what it actually changes about how work is planned, controlled and handed over, where it breaks, and which credential proves you can run it. Treat it as a decision aid rather than a ranking.

What separates one project management methodology from another?

Strip away the vocabulary and the eight approaches differ on one thing above all: when the scope is decided. Everything else – the ceremonies, the documents, the roles, the reporting – follows from that single choice. Decide the scope once at the start and you need change control, stage gates and a detailed plan. Decide it repeatedly as you learn, and you need short cycles, a prioritised backlog and someone empowered to say what comes next.

That gives three families, plus a deliberate blend:

The ‘Information Technology Infrastructure Library (ITIL)’ is a set of ITSM practices employed by some of the most prominent organizations in the world, including IBM, HSBC, and even NASA. Originally released as a series of books, ITIL was designed to standardize the procedures for proper IT management, helping businesses to evade the common obstacles to present the excellent quality services possible.

ITIL was first developed in Great Britain almost 20 years ago to generate a set of absolute best practices for utilization in government data centers. Since then, ITIL has been adopted, revised, and developed into a broad framework for directing IT service delivery in organizations of all scales and across industries.
