Overview

• The text has covered the first four stages of the core development processes in the SDLC.
• This chapter will cover implementation and deployment activities.
• Implementation activities include programming and testing, converting data, conducting training, configuring a production environment, and deploying the solution.
• Deployment activities are described in detail from iterative processes to core process.

Implementation and Deployment Activities

• A clear categorization of implementation activities and deployment activities is provided.
• The Core processes (Identify, Plan etc.) are described step-by-step.
• Iterations in development processes are shown (1 to 6 iterations).

Test Types

• Different types of software testing (unit, integration, usability, system, and stress) are categorized, described, and their operational characteristics are explained.

Testing Concepts

• The definition of testing as an examination to identify operational characteristics and potential defects.
• The definition of a test case, including start state, events, and expected response or non-functional requirements.
• The concepts of test data are described, encompassing conditions and events.

Unit Testing

• A definition of unit tests, which are examinations of individual components before integration.
• Driver methods and stub methods for testing are defined.
• Examples of driver methods and stub modules are presented.

Integration Testing

• The process of testing multiple components or modules is discussed.
• Potential failures - interface incompatibility, parameter issues, run-time exceptions, and unexpected state interactions.

Usability Testing

• A test to evaluate whether a method, class, subsystem, or system meets user requirements.
• Most common type evaluated on functional requirements—use case by use case.
• Usability tests consider learning ease and ease of use and whether results match actual requirements.

System, Performance, and Stress Testing

• An understanding of a system test of an entire system or subsystem is discussed.
• How daily or regular testing helps detect potential issues.
• Different types of system testing are covered, including build/smoke tests.
• Testing for performance and stress with criteria like response time and throughput.

User Acceptance Testing

• A system test to verify the system meets user requirements.
• These are usually toward the end of projects, sometimes after several iterations.

Deployment Activities (Detailed)

• A summary of deployment activities, including system and stress tests, user acceptance tests, data conversion, training, setting up a production environment, and deploying the solution.
• Iterations in the deployment process are shown.

Converting and Initializing Data

• The need for a complete database is explained.
• Data sources for populating the database, including existing files, manual records, and other systems, are identified.
• A diagram presents a complex data conversion process flow.

Training Users

• Training is needed for end users and system operators.
• Hands-on training for specific business processes like order entry, inventory control, and accounting is crucial.
• Training should address various skill levels with practice exercises, question-and-answer sessions, and tutorials.
• Training can be less formal for system operators who aren't end users, while experienced operators might learn through self-study.

Configuring the Production Environment

• The configuration of the production environment, depicting the different components required (servers, routers, firewalls, etc.) and their necessary placement within an IT infrastructure.

Planning and Managing Implementation, Testing, and Deployment - Development Order

• IPO (Input, Process, Output) development order.
• Top-down and bottom-up development orders, including stub and driver methods for testing.

Planning and Managing Implementation, Testing, and Deployment - Source Code Control

• An automated tool for tracking source code files and controlling changes to them.
• How a programmer uses read-only and read/write modes for accessing and modifying code files.
• The necessity for only one programmer to access read/write mode in code control systems.

Planning and Managing Implementation, Testing, and Deployment - Phased Deployment

• Describes a deployment method that installs a new system in phases, enabling gradual and controlled operational transition.
• Lists different approaches, including direct, parallel, and phased deployment.

Planning and Managing Implementation, Testing, and Deployment - RMO CSMS System Revisited

• The RMO decided to replace its old CSMS (Computer System Management System) due to infrastructure limitations and software obsolescence.
• The decision to replace was driven by factors including infrastructure limitations, age of the existing system, and an external vendor hosting.
• Phased deployment and data conversion were identified to minimize risk as well as database development and data migration before deployment.
• Order fulfillment, sales subsystem, documentation, and training are emphasized as key development components.

Planning and Managing Implementation, Testing, and Deployment - Iteration Planning Parts 1 and 2

• Describes the steps in planning and managing implementation, testing, and deployment, including essential use cases, class diagrams, and data migration.
• Iteration plans are shown that include processes such as defining the business models, establishing the environment, and making any necessary structural changes.
• Testing, including usability, stress, performance, and acceptance testing, is shown as integral parts of the stages, showing the various steps involving rigorous product verification.

Summary

• Implementation and deployment are complex due to dependencies between activities
• Implementation activities involve tasks like programming, unit testing, and component integration.
• Deployment involves tests (system, stress, acceptance), data conversion, training, production configuration, and solution deployment.
• Testing is critical and includes unit, integration, usability, system/performance/stress, and acceptance testing.
• Program development includes a complex trade-off involving resources, time, and the desire for prior error identification.
• Configuration and change management track modifications in models and software for different versions.
• Various deployment options like direct, parallel, and phased deployment were described.
• Implementing change activities include identifying affected system components, securing resources, scheduling activities, and developing test criteria.
• Supporting a system through multiple versions using tools and processes (Change and Version Control).
• Describing different versions of a system (Alpha, Beta, and Production/Release).
• Maintenance releases for bug fixes and changes in existing software.
