Background BYL Inc. Specialized in tax preparation software Provides over 100 firms across Canada with

personal and corporate tax software Has been released several versions of tax

software since 1999 Planning to release a new version

(SofTax08) in May. 2008 with new features

4

The Challenges

Try to meet all clients’ requirements Introduce new features to clients Generate reports in UML format for

development and easy-to-read documents for customers

Multiplatform required - WIN/UNIX Integrate tools into the company’s

environment – JAVA/Eclipse

5

What we need

We need to find tools can help us to: gather clients’ requirements review the design evaluate architecture decisions avoid holes and resolve conflicts validate and verify business needs

A effective GRL tool at the early stage Fit into the company’s environment

6

Why them

JUCMNav and OpenOME Well-known goal-oriented software

engineering tools Both have mature GRL functionalities

required Both are free software developed by

Canadian Universities Both are Java/Eclipse-based

7

Tools presentations

JUCMNav: jUCMNav is a graphical editor for the Use

Case Map (UCM) notation Created by five students supervised by

Professor Amyot at the University of Ottawa Open-source application available under the

Eclipse Public License (EPL) Uses the Eclipse Modeling Framework (EMF)

and the Graphical Modeling Framework (GEF)

First developed as a replacement for jUCMNav

User interface follows Eclipse standards jUCMNav takes advantage of the Eclipse

views (hierarchical/graphical outline, properties, resources)

Improved usability: drag & drop editing, group manipulation, unlimited undo/redo, …

Multiple element references Auto-layout mechanism Only allows the creation of syntactically

valid models

OpenOME: OME, Organizational Modeling Environment

Supports agent- & goal-oriented requirements engineering: NFR Non-Functional Requirements framework i* strategic actors modeling GRL Goal-based Requirements Language

Created at the University of Toronto OpenOME, extends OME as a Protégé plug-

in Visualize and Query Requirements Models

Supports elicitation and analysis of strategic requirements; Search and highlight views in the requirements goal models with knowledge management for the Semantic Web.

OpenOME is designed to be a goal-oriented and/or agent-oriented modeling and analysis tool

8

Evaluation criteria Usability

Evaluate aspects drawing features report generating and etc.

create model view model analyze model with user defined strategies and scenarios

Format of modeling Report (level of impact: High) Support of import/export formats

Compatibility with other tools (level of impact: High) Integrate with the IDE used in the company

Document (level of impact: Low) Help document & tutorial Quality of user manual

9

On Criterion – Create model

OpenOME:

create graphically clicks IE not as intuitive textually by define an

initial file in q7 syntax learning curve high

JUCMNav:

create graphically drag and drop more intuitive

10

On Criterion – View model

OpenOME:

visual GRL signs for evaluation results

label propagation can evaluate the satisfaction of high-level goals with respect to the label assignments to the low-level tasks

analyze model with user defined strategies

JUCMNav:

use numbers to evaluate results

number propagation can evaluate the satisfaction of high-level goals with respect to user init values to the low-level tasks using algorithm

analyze model with user defined strategies and scenarios

11

On Criterion – Import formats supported

OpenOME:

.tel (text) .vdx (XML)

JCUMNav:

JUCM SCENARIOS XML MSC contains UCM

Scenario

12

On Criterion – Export formats supported

OpenOME:

.tel .sml (Simple Markup Language) .vdx (Visio) .png (potable network graphics)

JCUMNav:

as individual diagrams (GRL): .dot .jpg .bmp .gif .png

as whole URN files: .dxl (DOORS Extension Language) .csm (optical tracking, 3d

format) .html .grl .csv

13

On Criterion – documentation

OpenOME:

not up-to-date, basic documentation & tutorials

JUCMNav:

up-to-date, detailed documentation, and tutorials

14

Methodology We developed several test cases for

evaluation criteria For each test case, we developed a scenario The test cases are designed to

record the behavior of each tool for each criterion preferably in quantitative manner if possible compare the results

Use testing results and examples to demonstrate

advantages disadvantages (of each tool)

15

Test cases Test case used to evaluate the Help document

Support TC-1: Create Model TC-2: Analyze Model TC-3: Generate Reports

16

OpenOME

17

JUCMNav

18

Test case 1: Create model According to the requirements from clients, create

models in OpenOME and JUCMNav

Checkpoints: Intuition and complexity GUI interface and ease of understanding, basic and

advanced operations Support copy and paste, undo, reuse of objects Help system

19

Test case 2: Analyze model Analyze created models under different scenarios

Checkpoints: Input from other projects Search and recalculate Validation & verification with business reality

20

Test case 3: Generate reports Generate analysis results in various formats Text-based and Graphic-based

Developers and customers

Checkpoints: Supported import/export formats – UML, XML, etc Model “Presentability” to stakeholders.

How can stakeholders understand models? Verification/Validation for conceptual models.

How can such (potentially large) models be verified? By stakeholders?

21

Conclusion

The purpose of the project is to make comparison between JUCMNav and OpenOME

From the business goal, we defined the sub-goals

From the sub-goals, we defined the evaluation criteria.

We developed test cases to evaluate the tools against the criteria

Right now, We are not able to recommend any tool , because the evaluation has not finished.
