Web-based Enterprise Resource Planning (ERP) Systems deployed through theSoftware-as-a-Service (SaaS) model are a major disruptive technology in the fieldof ERP systems. The defining features of the SaaS are that they are hosted remotelyand are completely used through the web; they are subscription-payment basedand they operate on a multi-tenant fashion. This technological innovation redefinestraditional technical and economic ERP paradigms. This Bachelor’s thesis aims through interviews with vendors, users and consultants,as well as by researching various academical and professional publications onthe subject of Web-based (SaaS) ERPs to study these pehomena, and produce a listof their benefits to SMEs. It also analyses their opportunities and challenges via anumber of interesting facts, thus allowing for thought-provoking observations andspawning of stirring discussions. The benefits of Web-based ERPs were reported to be similar to the ones characteristicfor the On-premise ERPs. They furthermore included remote data access, costefficiency,flexibility, scalability, as well as the esublishment of a new customerdrivenrelationship with the ERP vendor. The major disadvantages of SaaS wereconsidered to be security, cost (in the long run), and customizability. These disadvantages,which were first reported years ago, are continuously dismissed by theadavncements and innovations made in Web-based solutions. Findings from previousstudies and trends suggest that issues of security, cost and customizabilityare gradually disappearing as technology improves and industry dynamics becomesmore customer-centric. Security, which was a major issue in 2007 slowlyfaded and is not regarded as the concern it used to be. From 2008 till now the issuesof customizability and TCO have been heavily disputed about Web-based ERPsolutions. The problem of customizability has also been found to be diminishingdue to technologically advanced capabilities of these systems; new systems haveemerged and old systems have improved enough to provide this feature. Cost hasnever been a transparent issue when it comes to IT investments and has beenshown to be higher in On-Premise solutions through the TVO approach whichlooks at other hidden and non-financial costs. All of the above sheds new light intothe once-‘static’ benefits and drawbacks of Web-based solutions, and provides afresh insight into this developing phenomenon.

Många studenter behöver en web-baserad tjänst som de kan uppnå målet inom sina studier. Många studenter inom IT-området måste ladda ner mängder av programvaror och satsa relativt mycket pengar på sina datorer för att ha tillräckligt utrymme och processorkraft att köra olika program under sin studietid. Studenterna behöver en smidig, mångsidig och flexibel internetbaserad plattform som de kan komma åt när som helst, var som helst och från vilken enhet som helst. Dessutom är användbarhet hos plattformen en viktig aspekt för att supportera studenternas arbete. Bluemix är en Plattform as a Service (PaaS) - en typ av molntjänst. På Bluemix kan människor inom IT-området skapa, ändra, uppdatera och lagra sina applikationer med olika programmeringsspråk och de kan lägga olika tjänster till sina applikationer smidigt och snabbt. Syftet med den här uppsatsen är att utvärdera användbarhet av molntjänstplattformen Bluemix och undersöka vilken nytta som användare kan få när de använder plattformen. Den huvudsakliga målgruppen utgör studenter inom IT-området. Data har samlats in med hjälp av olika tekniker till exempel användartester, observation, tänka-högt (Think Aloud), intervju och enkät. Undersökningen visar att molntjänstplattformen Bluemix har god användbarhet fastän det finns några punkter som inte följer principer för god användbarhet. Dessutom är den en plattform som många testpersoner (studenter) önskar kan användas på universitetet.

Det finns många fördelar med att använda molntjänster och molnmarknaden har växt fort de senaste åren. Men när molnleverantörsmarknaden är så pass konkurrens utsatt är det inte lätt att välja vem man vill vända sig till, och det finns ofta anledningar till att vilja byta leverantör. Det finns många saker som kan låsa in en kund hos en leverantör, ofta på grund av att det skulle bli alldeles för dyrt att flytta, kanske för att ditt system inte är kompatibelt med någon annan leverantör, eller för att ett avtal hindrar dig från att flytta delar av systemet. Detta är vad man brukar kalla för leverantörsinlåsningar (vendor lock-ins). Många vill idag flytta system till molnet, men få är tillräckligt kunniga i vad det innebär och vad som kommer krävas från kunden. I den här studien vill vi belysa problemet och erbjuda vägledning till hur man kan minimera leverantörsinlåsningar.

Denna kandidatuppsats är en fallstudie av webblösningar och specifikt kring ekonomiprogram. Studien omfattar en undersökning för att ta reda på orsakerna till att inte fler småföretagare går över till webbaserade lösningar, detta är idag högst aktuellt eftersom det blir allt mer populärt att arbeta i molnet. Molntjänster är ett relativt nytt sätt att arbeta på och det innebär stora förändringar för företagen samtidigt som de erbjuder fler möjligheter än tidigare. I och med den ökade betydelsen av molntjänster och dess arbetssätt har vi även undersökt vad det finns för fördelar med webblösningar med hjälp av befintliga användare. Syftet med uppsatsen är att lyfta fram vilka som är orsakerna till att inte fler använder webblösningar, samt vilka fördelar det finns. Vår undersökning riktar enbart in sig mot ekonomiprogram, men kan med största sannolikhet användas i mer generella sammanhang. Metoden för undersökningen är en kvalitativ fallstudie, med intervjuer av ett flertal användare inom respektive arbetssätt.
