Writing and Reviewing Use-Case Descriptions
Bittner/Spence_06.fm Page 145 Tuesday, July 30, 2002 12:04 PM PART II WRITING AND REVIEWING USE-CASE DESCRIPTIONS Part I, Getting Started with Use-Case Modeling, introduced the basic con- cepts of use-case modeling, including defining the basic concepts and understanding how to use these concepts to define the vision, find actors and use cases, and to define the basic concepts the system will use. If we go no further, we have an overview of what the system will do, an under- standing of the stakeholders of the system, and an understanding of the ways the system provides value to those stakeholders. What we do not have, if we stop at this point, is an understanding of exactly what the system does. In short, we lack the details needed to actually develop and test the system. Some people, having only come this far, wonder what use-case model- ing is all about and question its value. If one only comes this far with use- case modeling, we are forced to agree; the real value of use-case modeling comes from the descriptions of the interactions of the actors and the system, and from the descriptions of what the system does in response to the actions of the actors. Surprisingly, and disappointingly, many teams stop after developing little more than simple outlines for their use cases and consider themselves done. These same teams encounter problems because their use cases are vague and lack detail, so they blame the use-case approach for having let them down. The failing in these cases is not with the approach, but with its application. -
Using the UML for Architectural Description?
Using the UML for Architectural Description? Rich Hilliard Integrated Systems and Internet Solutions, Inc. Concord, MA USA [email protected] Abstract. There is much interest in using the Unified Modeling Lan- guage (UML) for architectural description { those techniques by which architects sketch, capture, model, document and analyze architectural knowledge and decisions about software-intensive systems. IEEE P1471, the Recommended Practice for Architectural Description, represents an emerging consensus for specifying the content of an architectural descrip- tion for a software-intensive system. Like the UML, IEEE P1471 does not prescribe a particular architectural method or life cycle, but may be used within a variety of such processes. In this paper, I provide an overview of IEEE P1471, describe its conceptual framework, and investigate the issues of applying the UML to meet the requirements of IEEE P1471. Keywords: IEEE P1471, architectural description, multiple views, view- points, Unified Modeling Language 1 Introduction The Unified Modeling Language (UML) is rapidly maturing into the de facto standard for modeling of software-intensive systems. Standardized by the Object Management Group (OMG) in November 1997, it is being adopted by many organizations, and being supported by numerous tool vendors. At present, there is much interest in using the UML for architectural descrip- tion: the techniques by which architects sketch, capture, model, document and analyze architectural knowledge and decisions about software-intensive systems. Such techniques enable architects to record what they are doing, modify or ma- nipulate candidate architectures, reuse portions of existing architectures, and communicate architectural information to others. These descriptions may the be used to analyze and reason about the architecture { possibly with automated support. -

UML Tutorial: Part 1 -- Class Diagrams
UML Tutorial: Part 1 -- Class Diagrams. Robert C. Martin My next several columns will be a running tutorial of UML. The 1.0 version of UML was released on the 13th of January, 1997. The 1.1 release should be out before the end of the year. This col- umn will track the progress of UML and present the issues that the three amigos (Grady Booch, Jim Rumbaugh, and Ivar Jacobson) are dealing with. Introduction UML stands for Unified Modeling Language. It represents a unification of the concepts and nota- tions presented by the three amigos in their respective books1. The goal is for UML to become a common language for creating models of object oriented computer software. In its current form UML is comprised of two major components: a Meta-model and a notation. In the future, some form of method or process may also be added to; or associated with, UML. The Meta-model UML is unique in that it has a standard data representation. This representation is called the meta- model. The meta-model is a description of UML in UML. It describes the objects, attributes, and relationships necessary to represent the concepts of UML within a software application. This provides CASE manufacturers with a standard and unambiguous way to represent UML models. Hopefully it will allow for easy transport of UML models between tools. It may also make it easier to write ancillary tools for browsing, summarizing, and modifying UML models. A deeper discussion of the metamodel is beyond the scope of this column. Interested readers can learn more about it by downloading the UML documents from the rational web site2. -
The Timeboxing Process Model for Iterative Software Development
The Timeboxing Process Model for Iterative Software Development Pankaj Jalote Department of Computer Science and Engineering Indian Institute of Technology Kanpur – 208016; India Aveejeet Palit, Priya Kurien Infosys Technologies Limited Electronics City Bangalore – 561 229; India Contact: [email protected] ABSTRACT In today’s business where speed is of essence, an iterative development approach that allows the functionality to be delivered in parts has become a necessity and an effective way to manage risks. In an iterative process, the development of a software system is done in increments, each increment forming of an iteration and resulting in a working system. A common iterative approach is to decide what should be developed in an iteration and then plan the iteration accordingly. A somewhat different iterative is approach is to time box different iterations. In this approach, the length of an iteration is fixed and what should be developed in an iteration is adjusted to fit the time box. Generally, the time boxed iterations are executed in sequence, with some overlap where feasible. In this paper we propose the timeboxing process model that takes the concept of time boxed iterations further by adding pipelining concepts to it for permitting overlapped execution of different iterations. In the timeboxing process model, each time boxed iteration is divided into equal length stages, each stage having a defined function and resulting in a clear work product that is handed over to the next stage. With this division into stages, pipelining concepts are employed to have multiple time boxes executing concurrently, leading to a reduction in the delivery time for product releases. -

In RUP, project management is considered as core discipline whose activities are carried in all phases during development of software products. On other side service monitoring is considered as best practice of SOA which leads to availability, auditing, debugging and tracing process. In this paper, authors define a strategy to incorporate the service monitoring of SOA into RUP to improve the artifacts of project management activities. Moreover, the authors define the rules to implement the features of service monitoring, which help the project manager to carry on activities in well define manner. Proposed frame work is implemented on RB (Resuming Bank) application and obtained improved results on PM (Project Management) work. Index Terms—RUP, SOA, Service Monitoring, Availability, auditing, tracing, Project Management NTRODUCTION 1. I 2. RATIONAL UNIFIED PROCESS (RUP) Software projects which are developed through RUP RUP is a software engineering process model, which provides process model are solution oriented and object a disciplined approach to assigning tasks and responsibilities oriented.

Sysml Distilled: a Brief Guide to the Systems Modeling Language
ptg11539604 Praise for SysML Distilled “In keeping with the outstanding tradition of Addison-Wesley’s techni- cal publications, Lenny Delligatti’s SysML Distilled does not disappoint. Lenny has done a masterful job of capturing the spirit of OMG SysML as a practical, standards-based modeling language to help systems engi- neers address growing system complexity. This book is loaded with matter-of-fact insights, starting with basic MBSE concepts to distin- guishing the subtle differences between use cases and scenarios to illu- mination on namespaces and SysML packages, and even speaks to some of the more esoteric SysML semantics such as token flows.” — Jeff Estefan, Principal Engineer, NASA’s Jet Propulsion Laboratory “The power of a modeling language, such as SysML, is that it facilitates communication not only within systems engineering but across disci- plines and across the development life cycle. Many languages have the ptg11539604 potential to increase communication, but without an effective guide, they can fall short of that objective. In SysML Distilled, Lenny Delligatti combines just the right amount of technology with a common-sense approach to utilizing SysML toward achieving that communication. Having worked in systems and software engineering across many do- mains for the last 30 years, and having taught computer languages, UML, and SysML to many organizations and within the college setting, I find Lenny’s book an invaluable resource. He presents the concepts clearly and provides useful and pragmatic examples to get you off the ground quickly and enables you to be an effective modeler.” — Thomas W. Fargnoli, Lead Member of the Engineering Staff, Lockheed Martin “This book provides an excellent introduction to SysML. -
Ovum Decision Matrix: Selecting an Application Lifecycle Management and Devops Solution, 2019–20
Ovum Decision Matrix: Selecting an Application Lifecycle Management and DevOps Solution, 2019–20 Publication Date: 27 Jun 2019 | Product code: INT003-000374 Michael Azoff Ovum Decision Matrix: Selecting an Application Lifecycle Management and DevOps Solution, 2019–20 Summary Catalyst Software lifecycle management (SLM) is the management of software development by taking a lifecycle approach from concept through the management of requirements, testing, coding, deployment, upgrades, maintenance, and final retirement. The market provides tools to support this lifecycle in the form of application lifecycle management (ALM) tools and, with the rise of DevOps, tools that provide DevOps-style release management, orchestration, and automation. This Ovum Decision Matrix (ODM) examines ALM tools that cross over into DevOps to support the full arc of the lifecycle from application/product concept to deployment into production. Ovum view ALM origins and trends The need for taking an SLM approach is best thought of as good practice in the relatively young art of software development. The ALM tools market has evolved to support SLM through the years; at its core is the development methodology or work process, and this has evolved over time, starting with waterfall or linear stage-gate processes and incorporating various innovations such as Tom Gilb's evolutionary delivery, Barry Boehm's spiral model, and Rational's unified process, before Agile and lean swept the board with examples such as Scrum, extreme programming, and Kanban boards post- 2001 (when the Agile Manifesto was created). The integrated ALM suite tools market really took off around 2003 but supported waterfall because Agile was still under the radar. -
A Study on Process Description Method for DFM Using Ontology
Invited Paper A Study on Process Description Method for DFM Using Ontology K. Hiekata1 and H. Yamato2 1Department of Systems Innovation, Graduate School of Engineering, The University of Tokyo, 5-1-5, Kashiwanoha, Kashiwa-city, Chiba 277-8563, Japan 2Department of Human and Engineered Environmental Studies, Graduate School of Frontier Sciences, The University of Tokyo, 5-1-5, Kashiwanoha, Kashiwa-city, Chiba 277-8563, Japan [email protected], [email protected] Abstract A method to describe process and knowledge based on RDF which is an ontology description language and IDEF0 which is a formal process description format is proposed. Once knowledge of experienced engineers is embedded into the system the knowledge will be lost in the future. A production process is described in a proposed format similar to BOM and the process can be retrieved as a flow diagram to make the engineers to understand the product and process. Proposed method is applied to a simple production process of common sub-assembly of ships for evaluation. Keywords: Production process, DFM, Ontology, Computer system 1 INTRODUCTION (Unified Resource Identifier) is assigned to all the objects, There are many research and computer program for and metadata is defined for all objects using the URI. supporting optimization of production process in Metadata is defined as a statement with subject, shipyards. And knowledge of experienced engineers is predicate and object. The statement is called triple in embedded into the system. Once the knowledge is RDF. Two kinds of elements, Literal or Resource, can be embedded into computer system, the knowledge is not a component of a statement.
