What People are Saying About Astah

Mary Poppendieck - The author of "Lean Software Development" All companies face the challenge of transforming the knowledge of individuals into the wisdom of teams, then on to the collective vision of the company and the common knowledge of the industry. To the extent that companies meet the challenge of leveraging knowledge better than their competitors, they hold a significant competitive advantage. We have tried many things -documents, blueprints, even e-mails and conversations. Mary Poppendieck - The author of "Lean Software Development" But nothing is quite as effective as just the right set of concise diagrams and graphs that capture the essence of the situation. In the software development industry we have been searching for a common language to express knowledge, having discovered that neither documents nor casual conversations are adequate. In ChangeVision we have a great tool for helping us visualize the essence of the problem and merge the knowledge of individuals into the collective understanding of the development team.

" Mr. Hiranabe has been a strong and steady supporter of Extreme Programming in Japan since it first became publicly known. He has communicated and adapted XP to make it more useful to Japanese programmers. Now he is bringing XP and other software development improvements to a larger market with his tools and consulting services. I look forward to seeing what he accomplishes with his new company, Change Vision"
-Kent Beck - USA
"Very cool UML tool. Simple and intuitive but remarkably powerful. Supports color coding in classes so it can be used for the Agile Modeling with Color technique."
-Vernon Stinebaker
"I looked and tested many UML softwares, open-source or commercial... No more need to seek, I found Astah UML! It is really a great tool, user friendly, with rich functionalities and lightweight... I often use it for reverse engenering, to maintain my classes model, and in order to export diagrams to build fine documents."
-Jerome Raduget - France
"In my years of experience in the software development industry, there has always been a recurrent question, "Which tool shall the team use to prototype, discuss or document a class design?" The tool that has always best answered that question is Astah UML. I have always used either in the job or in my graduate studies or for my Design Patterns open source project. Astah is simply a must have in any professional software development environment."
-Giovanni Azua - Switzerland
"Astah has helped me in my projects many times. I found it a very powerful and easy to use tool in comparison to other programs."
- Andrzej Wislowski - Poland
"I was very satisfied by your product specially because I spent quite some time trying several UML design tools, then I found Astah. That's why I sent the tweet you read, and even convinced a colleague to try it."
-Carmen Brando - France
"I have used several UML tools since mid-90's from RationalRose to EA, but all seems to be not quite enough. Every tool has its quirk and you need to know a way to handle them. To write my UML introduction book, I used Astah for figures and practices as it's a well-known UML tool. Astah seems to have been much refined overall over these years."
-Akio Kawai - Japan
"Have used a myriad of UML tools but found Astah to be very lightweight, sufficiently complete, and great for modeling at an abstract-level without being implementation-specific."
- Johannes Kuah - Singapore
"I use Astah for works at university. Astah is a very welcome help when we need to see an overview of full project. I really love the simplicity and ability to align objects automatically like on canvas. Thanks Astah! You rock!"
-Helder Cesar - Brazil
"I found Astah UML really impressive. My practice of listing requirements using a mind-map, then drilling down with class and sequence diagrams as system design proposals and then let the design evolve as part of scrum activities. I found Astah worked very well my style of delivery (especially with Agile)."
- Premnath, KN - India
"Hiranabe-san has been a leader in the Japanese Agile and XP (software development) movements. He is recognized for having outstanding technical and leadership abilities, and brings to the company the necessary deep understanding of the breadth of the field and the particulars of the Japanese culture. He is also sensitive to the human cultural factors involved in evolving an organization. Change Vision is fortunate to have Kenji Hiranabe-san in its leadership team."
- Alistair Cockburn - USA
"I have spent so much time looking for a UML tool that suits my needs and runs on different platforms (especially Linux). When I first tried Astah, I immediately felt comfortable with it, so I tested Astah with some real-life models. What surprised me was that creating sequence diagrams in Astah feels so "natural", especially the versatile message numbering. This convinced me to use Astah, which is now my UML tool of choice"
- Klaus Hinderer - Germany
"My first experience with Astah was on the iPad. I instantly felt at home with the intuitive interface. When I learned shortly afterward about the desktop application I was delighted that I could directly import my preliminary designs for refinement. At this point it has replaced my default modeling tool. I plan to use it extensively in the coming months. The developers of Astah were also very responsive and gracious when I contacted them about the product. Overall, I couldn't be happier!"
- Connor Doyle - USA
"Astah UML Pad really helps because I'm always short of time and it's hard to get many contiguous hours in front of the computer for project work. Instead, I can use Astah to progress my project on the train or even when I'm baby-sitting! I can be clear on my designs so that I can make efficient use of 'coding time' and even though I'm building fast, I can keep code quality to a maximum because I've had the chance to think it through properly beforehand."
- John Greenhow - Australia
