Designing Mobile-based Application for Quantifying IT Business Value

North Sulawesi province is fostering regional development towards a society which have values, prosperous and competitive cultures. Information Technology (IT) have become a key enabler to accelerate region developments. To optimize IT utilization, local government can used IT Valuation Matrix framework, to identify all IT Business Value which derived from each IT investing type, and then be quantify in reasonable and responsible manner. IT Valuation Matrix framework also provide best practices to assessing local government IT investment. This article shows the process of designing mobile-android based applications for quantifying IT Business Value based on IT Valuation Matrix method. Using Disciplined Agile Delivery methodology, which based on agility and object-oriented approach, the application that meet user expectations and needs, can be developed.


Introduction
The business realization benefits of IT (or IT business value) [1][2][3] defined as benefits or results obtained from an IT investment which can improve organization performance.IT business value is more than just provide a benefit in financially terms.The IT business value concept includes on how IT provides efficiency, effectiveness, increase productivity and create competitive advantage for a particular organization.
This IT business value understanding follows Parker [4] [5] , where according to Bannister and Remenyi [6] based on Porter [7] definition about value.This article will follow IT business value definition proposed by Ranti [1][2] .
The objective of this article is to demonstrate the analysis and design process of the application for Quantifying IT Business Value based on Ranti's IT Valuation Matrix Method.This application was developed using agile-approach methodology, called Disciplined Agile Delivery (or DAD).

IT Investment Analysis
IT investment analysis, according to Ranti [2][3] was done based on several reasons, namely: To have a justification of IT projects, to enable organization assessing investment of various IT projects undertaken with limited resources, to provides a tools for controlling and monitoring IT investments that have been and will be done, and to enable organization create competitive advantage, develope new business, improve performance and productivity, and provide new ways for managing the organization.Ranti [1] develop an IT Investmant analysis method based on the business value of IT.This method is called IT Valuation Matrix.Ranti [1] also takes into account the financial and non financial approach.(See Figure 1).Ranti [1] framework begin with classifying the investment type according to the category of mandatory, improvement, strategic and infrastructure, where each category have different focus, assessment, value and quantification process.Wowor and Karouw [8] using Ranti's IT Valuation Matrix method to quantify the identified IT Business Value for Local Government.Using case study approach for North Sulawesi Province, as service-oriented organization, Wowor and Karouw [8] expand Ranti's IT Valuation Matrix method with IT Business Value Identification and Classification phase, before Quantification stage.Wowor and Karouw [8] also added Clarification Process stage after conduct the Quantification stage for all identified IT Business Value.(see Table I).

TABLE1
CLARIFICATION PROCESS [8]  Formal definition for DAD is a people-first, learning-oriented hybrid agile approach to IT solution delivery.It has a risk-value lifecycle, is goal-driven and is enterprise aware.The DAD process framework is a hybrid: i.e it adopts and tailor strategies from a variety of sources [10] .See Figure 2 for The DAD Process Framework.

Analysis and Design
This article show the analysis and design process for build application for quantifying IT business value based on IT Valuation Matrix, proposed by Ranti [1] .Following stages conducted by Wowor and Karouw [8] , this application will compute two category of identified IT business value, which Reducing Cost Of (RCO) and Reducing Risk (RRI).For this mobile android version, we have add new features such as Add New Project and Project List.The business process running by this application is shown at Figure 3 and Figure 4, using UML Activity Diagram.

Inception Phase
The main target of inception phase is to understand the scope and objectives of the project and obtain enough information to confirm that we must go on or no.Main result for this phase is User Requirements.User Requirements have major impact for application development.The artifact which produced user requirements list are called User Stories Card [12] ., the application estimation process will be compute easily.Table 3

Construction Phase
Construction phase is the next stage in the software development lifecycle according to DAD.The target of this phase is to determine the base architecture of the system and building working application code follows the base architecture.The major artifact resulted from this phase activities is Software Architecture Document (SAD).Mostly, SAD document provides the architecture model for the whole software application system.For this research, author using UML 2.0 [14] as tools for application models as Fowler proposed [15] .
We used UML Use Case Diagram and Use Case Descriptions as functional requirements model.However, the complete list of UML Use Case Description are not presented in this paper.Figure 4 depicted UML Use Case Diagram as Functional View Model for this application.This use case model will guide through all construction process.
Interface design is the process of defining how the system interacts with an external unit.The user interface consists of three basic parts.The first is the navigation mechanism, a way of giving instructions to the user and the system tells the system what to do, such as buttons and menus (see Figure 5).The second is the input mechanism, a way of capturing information system (e.g a form to add news).The third is the output mechanism of how the system provides information to users or to other systems (e.g reports, web pages).(see Figure 6).

Transition Phase
The main target of the construction phase is efficient and inexpensive development of the end product, that is, a version of the operational system that can be deployed to the end-user community.The designing and construction of this application is using Android Developer Tools version 22.3.4-8878.26Android 4.0.

CONCLUSION
This paper show the analysis and design process to develop application for quantigying IT business value which follow IT Valuation Method proposed by Ranti [1] .As Wowor and Karouw [8] conduct, process for quantification and clarification can be done for category Reducing Cost Of (RCO) and Reducing Risk (RRI).Some conclusions from the writing of this paper include: 1) The DAD process framework can be used as guidelines to design mobile-based application for non-profit organization, such as local government.This process framework promote agile-approach and object-oriented paradigm, so can ensure software delivery faster.
2) The Mobile version Application for Quantifying IT Business Value must be develop comprehensively for all identified IT Business Value proposed by Ranti's IS/IT Generic Business Value.
