As it turned out, Johan’s presentation was one of the most popular sessions of the event. During his presentation, Johan elaborated on the use of DSL’s (Domain Specific Languages), model interpretation and ways to embed custom Java code into Mendix applications. The icing on the cake was a demo using our latest release; the long- anticipated version 2.5 of the Mendix platform.

Visitors were surprised with the ease of use and the speed with which Johan was able to build up an order entry system from scratch. His demo proved to attendees that by empowering business analysts with the right tools, the business world is in for a whole new game of Business Agility Management.

Are you under pressure to deliver more from less?

Today’s business organisations operate in an increasingly tough environment, from a competitive, financial and regulatory framework perspective. Whichever direction pressure comes from, one thing is certain: organisations cannot keep still if they want to survive, so IT applications and systems need to change and adapt to new business landscapes. The need for this constant renewal demands agility and flexibility, to reduce cost and time-to-market and to ensure that solutions are aligned with business strategy and continue being so when strategy changes.

Agility and Model Driven Solution Delivery

Agile software development has recently been embraced by a large number of organisations. One of the key tenets of the agile approach is that code is master, and models and documentation are secondary artifacts. However, producing and maintaining code continues to be a time consuming and error-prone task.The reasons are not hard to imagine: there is a long distance to bridge between business requirements and code expressed in languages like Java and C#, with all the errors and distortions that can be produced on the way, and associated validation and testing costs. In addition, the people who best understand the requirements, i.e. business people and business analysts, are not directly involved in the development of the solution, opening the way to misinterpretation and miscommunication errors. Model Driven Delivery (MDD) brings the business analyst into a central development role. Code is no longer master, in fact it becomes almost irrelevant. MDD empowers the business analyst to create solutions to business problems using visual models that are much closer to the business requirements than low-level artifacts such as program code. Not only are the resulting solutions of higher quality as a result of the level at which they are stated, but the time and cost of developing them are dramatically shortened. MDD has been around for some years, however most existing platforms adopt the code-generation approach, in which the solution is always made up of program code, and models have to be translated into code before they can be executed. So code ends up being, if not the master, the key executable artifact, which has to be tested for correctness if not maintained independently from the models.

Why Choose RDF and Model Driven Delivery?

RDF have partnered with a leading MDD vendor, Mendix, whose product is arguably the most advanced MDD platform on the market. With Mendix, models produced by the business analyst are directly executable by a run-time engine, with no need to generate executable code. So where has the complexity gone? The answer is that business logic complexity has not gone away, and is tackled by the analyst at the modelling level. What has gone away is the technical complexity of designing and writing program code.

This new approach therefore demands a high degree of precision and detail by the business analyst, as all data definitions, flow rules, business rules, screens etc, need to be defined completely and precisely in order to be executable. Unfortunately a large number of business analysts are good at understanding business but not so good at documenting their thinking precisely, having always postponed detailed specifications to the coding stage. At RDF, we have used for many years a modelling approach that demands precise and complete models, to avoid having to make business decisions at the coding stage. Hence our analysts are ideally placed to work with the Mendix MDD platform. Our developers are also well placed to become modellers, as they also have been exposed to modelling languages in their design work. In addition, the Mendix platform allows actions to be defined within the model, and implemented in Java if necessary, leveraging the Java skills which are in abundance at RDF.

Benefits

• Reduced time to market: Models are the only artifact to be produced, so the development cycle is reduced by a factor that can range from 50% to 80%, according to the nature of the requirements.
• Reduced development effort: This is a consequence of the reduced timescales, and also of the reduction in team size and number of development and validation activities in the life cycle.
• Increased flexibility: Adapting a solution to a new set of requirements is more direct, hence faster and less expensive, with the same savings cited above for development of new solutions.
• Business alignment: Models are much closer to business requirements than code. MDD facilitates fast iterations with frequent feedback from business people, ensuring that solutions stay in line with business expectations.
• Easy Integration: The Mendix framework adopts open standards for easy integration with existing platforms and components, whether within the organisation or across the value chain.
• Rich and dynamic user interface: The Mendix framework uses a personalised web client, based on Ajax technology. You can also run Mendix solutions in your portal environment.
• Performant and scaleable solutions: The Mendix run-time engine is optimised for high performance and runs under any J2EE Application Server, so it can work in a clustered, scaleable environment.

Conclusion

True business agility and flexibility comes when business is freed from the tyranny of code. Try the MDD approach from RDF and you’ll never look back.

Op vrijdag 13 februari jl. mochten wij 75 bezoekers begroeten op de gecombineerde Essentials bijeenkomst van BiZZdesign en Mendix. Het doel van de Essentials was om het publiek te informeren over de combinatie van procesontwerp en procesondersteuning, met bijbehorende toolondersteuning. Het was een informatieve en interactieve sessie, waarbij er na afloop druk werd nagepraat over de bijgewoonde presentaties en demonstraties.

De bijeenkomst begon met een overzicht door Derek Roos (Mendix) van het speelveld van procesontwerp en procesondersteuning, waarbij een aantal herkenbare probleemsituaties rond de afstemming van business en IT aan de orde kwam. Vervolgens werd er door Harmen van den Berg (BiZZdesign) dieper ingegaan op het ontwerpen van processen, en de rol van procesmodellen daarbij. Hierbij werd de tool BiZZdesigner uitvoerig gedemonstreerd, waarbij de verscheidene views op proces, rollen en systemen aan bod kwamen. Er werd daarnaast ook ingegaan op meer geavanceerde procesanalyses zoals doorlooptijden, wachttijden en bezettingsgraden voor proces en actoren. Tijdens de bijeenkomsten werden een aantal vragen gesteld over versie- en modelbeheer, iets waar goed in voorzien is in BiZZdesigner.

In het tweede deel van de bijeenkomst werd door Derek Roos verder ingegaan op het creëren van procesondersteunende applicaties op basis van procesmodellen. Het Mendix-platform maakt het mogelijk om applicaties te ontwikkelen op basis van procesmodellen, hetgeen de snelheid en flexibiliteit sterk verbeterd in vergelijking tot meer traditionele software ontwikkeling. Derckjan Kruit en Fedor Klinkenberg (Mendix) lieten dit zien in een demonstratie van het Mendix platform. Daarbij werd als eerste stap een procesmodel uit BiZZdesigner via een XPDL-export ingelezen in het Mendix-platform. Dit model werd vervolgens verrijkt met gegevens en business rules. Vervolgens werd dit model “gedeployed”, zodat een werkende applicatie ontstond.

Na afloop van de presentaties en demonstraties werd onder het genot van een hapje en een drankje nog stevig doorgepraat.

Op veler verzoek en voor iedereen die onverhoopt de Essentials heeft moeten missen hebben BiZZdesign en Mendix de presentaties zoals gegeven op de Essentials online beschikbaar gemaakt.

BiZZdesign-Mendix presentatie

Wij kijken terug op een zeer geslaagde Essentials-bijeenkomst, met een hoge opkomst en veel interesse vanuit de deelnemers. Wij hopen dat u als deelnemer een goed overzicht heeft kunnen krijgen welke mogelijkheden er zijn om van procesontwerp tot procesondersteuning te komen.

Mendix

On J-Fall 2008 Mendix and Centric teamed by jointly exhibiting at another successful Java conference organized by the NLJUG. J-Fall proved a great event to get in touch with the Java community and to demonstrate the Mendix platform in front of a live audience.

See you again at J-Spring 2009!

The Mendix & Centric booth

Johan den Haan explains

De dag wordt georganiseerd door Mendix en zal geheel in het teken staan van de nieuwste ontwikkelingen in de markt en bij Mendix. Het programma staat onder leiding van Mendix maar bestaat uit presentaties en lezingen van diverse (onafhankelijke) experts uit het veld. De opening en keynote lezing wordt verzorgd door Maarten Steen van het Telematica instituut en er zullen praktijkervaringen worden gedeeld door o.a. Sanoma Uitgevers en Magnus Management Consultants.

Derek Roos, CEO van Mendix is verheugd over het evenement: “Model-driven Development is de toekomst van software ontwikkeling in de zakelijke sector, omdat hierdoor de ontwikkeling van software aanzienlijk korter en flexibeler wordt. Bovendien kunnen de kosten laag worden gehouden doordat werknemers van het eigen bedrijf nauw betrokken zijn bij de applicatie ontwikkeling.”

Roos voegt hieraan toe dat modelgedreven software ontwikkeling voor veel bedrijven nog onbekend terrein is en dat dit de belangrijkste reden is voor het organiseren van de Mendix Model Experience. “In een wereld die steeds kleiner wordt en de internationale concurrentie sterker, is het enorm belangrijk dat organisaties flexibeler worden, hogere kwaliteit gaan leveren en liefst tegen lagere kosten. Op de Mendix Model Experience willen we “live” en door middel van echte klant casussen laten zien dat modelgedreven ontwikkeling écht is en onvermijdelijk voor iedere organisatie die blijvend wil concurreren.”

Aanmelden

Mendix nodigt iedereen die op de hoogte wil blijven van de nieuwste software ontwikkelingen van harte uit om aanwezig te zijn bij de Mendix Model Experience op 31 oktober in het World Port Center te Rotterdam. Het belooft een leerzame en interactieve dag te worden met een fantastisch uitzicht over de Rotterdamse skyline en het Nederlandse IT landschap.
