The CYBEX Sirona S is the only convertible car seat to feature a 360° rotatable seat with load leg stability, linear side impact protection, and SensorSafe technology.

With SensorSafe technology, you'll gain instant insight into your child's well-being-right to the SensorSafe app on your phone. Built into the chest clip of Cybex car seats, SensorSafe provides alerts when unsafe situations arise including if a child unbuckles themselves; if the back seat has become too warm or too cold if a child has been seated for too long, and if the driver accidentally leaves the child behind.

Essential Resource for Agile Practitioners and Exam Prep
Format: Paperback
The Agile Practice Guide by PMI is an indispensable resource for anyone looking to understand and implement agile methodologies. As someone preparing for the CAPM exam (or working in project management), I found this guide incredibly clear and concise. It effectively breaks down complex agile concepts into digestible information, making it easy to grasp the core principles. It's not just theoretical; it provides practical insights that are directly applicable to real-world projects. A must-have for both certification candidates and active project managers.

As always, I gave due diligence to this product review
Format: Kindle
I am back once again. As always, I gave due diligence to my reviews. To those of you who found my ratings of multiple PMP publications helpful, you will want to read on. See collective ratings under “Michael Henry” https://www.amazon.com/Project-Management-Professional-Certification-Exam/dp/1492310549/ref=sr_1_3?crid=1CXATM61H9GX&dchild=1&keywords=sohel+akhter%2C+exam+prep+book%2C+6th+ed&qid=1606711795&sprefix=sohel%2Caps%2C230&sr=8-3
That said, all my Agile book reviews are Verified Purchases.
Now let’s get down to business shall we. This time around I decided to rate multiple Agile Guides using the same criteria listed on my PMP Guide Evaluations. Obviously, it was necessary to revise/tailor the criteria to meet the unique requirements for Agile-based project management versus the Traditional Waterfall approach. In other words, my ratings were based on how well a given Agile publication satisfies requirements as defined by PMI, AgileAlliance.org and applicable industry standards. As for why I chose to evaluate Agile-based guides is simple. It is my understanding that PMI will be instituting new guidelines regarding their PMP certification requirements. Part of the new requirement will include testing for proficiency in the application of Agile Methodologies (50% of PMP Exams?). More importantly, I happen to know (I have many contacts in major industries) major players such as Lockheed Martin, Northrup Grumman, Apple, Boeing, Raytheon, and various pharmaceutical companies are all looking to migrate their systems over to an agile-based project model. It has come to my attention that executive management teams have been chartered by the CEO’s of these companies, with making the transition to the “Agile Way” going forward. Assuming my assertion is true, it is in your best interest to start preparing now if you expect to stay current given the paradigm shift slowly but surely coming our way. Change is hard but it is necessary!
After poring over 11 comparable guides, here is what I came up with:
Agile Rating Criteria:
A) Cost.
B) Dual Purpose Feature (DP). Answer depends on whether Guide offers Guidance on Agile project selection/management *AND* Agile PMI-ACP compliant test questions that cover all chapters.
C) Level of Comprehensive test (where applicable) and content coverage.
D) How consistent chapter focus is aligned with percentage of test questions.
E) Multiple methods of presenting the same material to increase comprehension through redundancy.
F) How well diagrams, tables, graphs, charts, and presentation material were utilized to provide a contextual understanding of various Agile methodologies.
G) Coverage of test taking strategies for deciphering test questions.
H) How well test questions answers are explained at the end of each chapter.
I) Using Real-life case studies to “drive home” complex and/or complicated constructs (look it up if you don’t know the difference between the two).
J) Online test bank availability.
GUIDES I PURCHASED AND REVIEWED:

2nd place: Author Joseph Phillips: “ALL-IN-ONE PMI-ACP Agile Certified Practitioner, Exam Guide. (dual purpose) (5 stars)
3rd place: Author Konnor Cluster: “AGILE PROJECT MANAGEMENT, Learn How to Manage a Project with Agile methods, Scrum, Kanban, and Extreme Programming.”(4 ½ Stars) *AND* Author PMI: “Agile Practice Guide.” (4 ½ Stars)
Honorable mention: All 4 Star ratings
***Special Note: I chose not to include publications targeted for Beginners (don’t want to be accused of comparing apples to oranges).
For the record, I will be posting these evaluations for 1st 2nd 3rd place and “honorable mention” reviews only.
For those of you wondering why I chose to evaluate 11 Agile Guides. The answer is simple, rating these guides not only enhances my understanding of the various Agile based project management methodologies, it also allows me to continuously improve my knowledge base relative to the current advances being made in the field of project management, across a wide array of industry types. It’s all about staying informed lest you want to get left behind.
In closing, I hope you all find my effort to provide guidance, when selecting an Agile Guide Publication, useful!

Good Information, But Poorly Made
Format: Paperback
Educational and I was getting it to assist with getting my PMP. However my only criticisms about the book is that there is a ton of empty space on the pages. I think there would’ve been a better more environmentally friendly way to compact the information in the book. In addition it is very hard to read the book when the spine is constantly spreading apart. I’m afraid that the book pages are going to rip off one time or another. They haven’t yet but it is a concern.
