This document discusses various methods for determining system requirements, including interviews, questionnaires, observation, document analysis, Joint Application Design (JAD), prototyping, and business process reengineering (BPR). Interviews can use open-ended or close-ended questions, and preparation is important. Questionnaires must be carefully designed and can include both open-ended and close-ended questions. JAD brings together key stakeholders to simultaneously collect requirements. Prototyping converts early requirements into a working system for user feedback. BPR aims to radically improve processes through reorganization and leveraging disruptive technologies.

A Water Fall Model is easy to flow.
It can be implemented for any size of project.
Every stage has to be done separately at the right time so you cannot jump stages.
Documentation is produced at every stage of a waterfall model allowing people to understand what has been done.
Testing is done at every stage.
This model was not the first model to discuss iterative development.
As originally envisioned, the iterations were typically 6 months to 2 years long.
Each phase starts with a design goal and ends with the client (who may be internal) reviewing the progress thus far.
Analysis and engineering efforts are applied at each phase of the project, with an eye toward the end goal of the project.

Structuring software systems with OSGi - Ulf Fildebrandtmfrancis
OSGi is providing a module system, but during implementation in projects it becomes difficult to really use the benefits of an OSGi runtime. Without follow the principles an OSGi system can evolve to a tightly-coupled system like in the past. Some principles and guidelines have to be followed to achieve a good architecture of a software system: - interface/implementation separation for bundles - visibility usage of bundles (import/export) - extensibility for services (and special focus on declarative services) - layering of bundles and using declarative service for layer communication - mocking of layers to achieve maturity of the implementation - interface evolution of bundles to achieve extensibility The presentation will show the changes by refactoring a small web application. The application starts as a tightly coupled system and will be improved by applying the architecture principles. So, in the presentation a lot of coding will be shown, until a good structure of the application is achieved. The guidelines are based on experiences in different projects and are used as best practices in new projects.

Determining Requirements In System Analysis And DsignAsaduzzaman Kanok
Requirements determination and requirements structuring are two core components of system analysis. Traditionally, interviewing, questionnaires, directly observing and analyzing documents are four main methods adopted by system analysts to collect information. JAD and prototyping are two modern requirements determination methodologies, which are developed and based on the previous traditional methods. A well-structured representation of system requirements can dramatically improve the communication among analysts, designers, users, and programmers. DFD, structured English, decision tables, decision trees, and E-R diagrams are traditional primary requirements structuring tools. Nowadays, RAD and OOA are emerging to help streamline and shorten the total SDLC. While RAD SDLC packs traditional analysis phase and part of design phase into one step, OOA tries to make the outcomes of analysis phase can be reused by the following developing phases

Enhancing Research Orchestration Capabilities at ORNL.pdfGlobus
Cross-facility research orchestration comes with ever-changing constraints regarding the availability and suitability of various compute and data resources. In short, a flexible data and processing fabric is needed to enable the dynamic redirection of data and compute tasks throughout the lifecycle of an experiment. In this talk, we illustrate how we easily leveraged Globus services to instrument the ACE research testbed at the Oak Ridge Leadership Computing Facility with flexible data and task orchestration capabilities.
Providing Globus Services to Users of JASMIN for Environmental Data AnalysisGlobus
JASMIN is the UK’s high-performance data analysis platform for environmental science, operated by STFC on behalf of the UK Natural Environment Research Council (NERC). In addition to its role in hosting the CEDA Archive (NERC’s long-term repository for climate, atmospheric science & Earth observation data in the UK), JASMIN provides a collaborative platform to a community of around 2,000 scientists in the UK and beyond, providing nearly 400 environmental science projects with working space, compute resources and tools to facilitate their work. High-performance data transfer into and out of JASMIN has always been a key feature, with many scientists bringing model outputs from supercomputers elsewhere in the UK, to analyse against observational or other model data in the CEDA Archive. A growing number of JASMIN users are now realising the benefits of using the Globus service to provide reliable and efficient data movement and other tasks in this and other contexts. Further use cases involve long-distance (intercontinental) transfers to and from JASMIN, and collecting results from a mobile atmospheric radar system, pushing data to JASMIN via a lightweight Globus deployment. We provide details of how Globus fits into our current infrastructure, our experience of the recent migration to GCSv5.4, and of our interest in developing use of the wider ecosystem of Globus services for the benefit of our user community.

First Steps with Globus Compute Multi-User EndpointsGlobus
In this presentation we will share our experiences around getting started with the Globus Compute multi-user endpoint. Working with the Pharmacology group at the University of Auckland, we have previously written an application using Globus Compute that can offload computationally expensive steps in the researcher's workflows, which they wish to manage from their familiar Windows environments, onto the NeSI (New Zealand eScience Infrastructure) cluster. Some of the challenges we have encountered were that each researcher had to set up and manage their own single-user globus compute endpoint and that the workloads had varying resource requirements (CPUs, memory and wall time) between different runs. We hope that the multi-user endpoint will help to address these challenges and share an update on our progress here.

Once the user sees requirements converted
to system, will ask for modifications or will
generate additional requests
Most useful when:
User requests are not clear
Few users are involved in the system
Designs are complex and require concrete form
History of communication problems between
analysts and users
Tools are readily available to build prototype
7.19
20. Prototyping
