What’s shaping the Business Systems of the Future With the abundance of desktop and mobile devices and platforms, there are now numerous ways for consumers and information workers alike to create and consume applications and services. Enterprise applications are having to evolve to keep up, and your ERP system is no exception – like all other applications, they too need to move with the times. The session focussed on emerging trends in business solutions from Microsoft and a forward looking view on what Microsoft Dynamics ERP might look like in the future. In this session, we covered: - How business processes can be embedded into users’ own devices - How social systems are influencing business system design – how Microsoft Dynamics is responding to the growing influence of social systems - Previewing design concepts for the future versions of Dynamics ERP applications, including a Metro-based application Presented by James Page and Nick Johnson of Intergen along with Sue Driscoll of Microsoft, this session provided an exclusive behind the scenes look at how Microsoft’s ERP solutions could evolve in the future. While the focus of the session was on Microsoft Dynamics, this session could also be of interest to those people who want an insight into how enterprise systems in general are having to evolve to keep up with new devices and interaction methods.

Organisations that embrace cloud computing can experience significant cost reductions when it comes to the on-going operation of their solutions. With Dynamics NAV 2013 now available as a cloud-based solution, Microsoft is one of the few vendors about to provide organisations with options when it comes to ERP deployment. Is your organisation ready to embrace ERP in the cloud? What are the key business factors you should be considering? What should we, as New Zealand-based organisations, be looking for? Does an on-premise deployment make more sense? This Think! Seminar explored the value proposition of ERP in the cloud, incorporating the latest information from Microsoft Convergence, Microsoft’s global conference for users of Microsoft Dynamics solutions.

A todos nos pasa. Tu mejor vendedor te pide “un minuto para platicar.” Sabes que no vas a escuchar nada bueno. Piensas en lo difíciles que estuvieron las ventas el año pasado. En esos dos dígitos de crecimiento que prometiste para este. Y en cómo le harías si te deja ese vendedor. O peor aún, si se va con tu competencia. Pagar poco desmotiva a cualquier vendedor. Pero pagar más no ayuda. Las comisiones ni siquiera están entre los 3 principales incentivos que motivan a un vendedor. ¿Cómo le haces? En Oracle enfrentamos este problema a diario y hemos visto todos los errores posibles a la hora de motivar a un equipo de ventas. Queremos compartir contigo lo que hemos aprendido. Aquí conocerás: - Cuáles son los errores más comunes en un plan de incentivos para ventas. - Qué comportamientos desgastan a tus top performers. - Qué tener en cuenta a la hora de ajustar tu plan de incentivos.

Robotic process automation (RPA) is changing business processes in almost every industry by streamlining data entry and other low-level tasks. Presently the innovation, which populates digital forms in a small amount of the time it takes people to do likewise, is getting a long-overdue upgrade. Progression in machine learning (ML) and artificial intelligence is making businesses ready for intelligent automation (IA), a more brilliant brand of RPA that figures out how to execute entire business processes with context, instead of as a progression of discrete tasks. However, most companies have much bigger fish to broil than simply keeping operational costs low and bridging technology gaps. Also, with regards to really delivering business results from on-time delivery to income growth or the elusive customer experience, RPA is actually a small piece of a lot bigger picture

Speech of Orban Botond, Ruby Developer at Toptal, at Ruby Meditation 27, Dnipro, 19.05.2019 Slideshare - Next conference - http://www.rubymeditation.com/ Software development is a domain where everybody can make a beautiful sculpture or can quickly build an unsolvable maze. According to my observations the later happens more often unfortunately. In the title for my presentation both the If Jungle and the Civilised Railway Station are methaphors representing the opposite ends of the scale of quality code. In my presentation I am going to present my personal experiences on how to get out from the trap of the if jungle by making the code to adhere to the SRP and DRY principles. I am also going to show the advantages of the Railway Oriented Programing using the 3 different libraries. The examples are going to be stereotypical errors, fun and easy to follow.
