Can a similar shift be made within Enterprise ApplicationDevelopment?

Can we afford not to TRY to make such a shift? 4

Current State…

>45%of customers experienceproduction delays

>50%of outsourcedprojects fail tomeet objectives

>70%of budgets devotedto maintenanceand operations

A IDE brings to the table…Instead of maneuvering to access panels and working sequentially, in RDz the functionality you need is always

in-focus – you work concurrently using “built for developer” features productivity

zUnit – Unit testing framework for z/OS

• Frameworks that assist developers in writing code to perform repeatable, self-checking unit tests arecollectively known as xUnit.

• xUnit defines a set of concepts that together provide a light-weight architecture for implementing unittesting frameworks.

• JUnit, for example, is a very popular instance of the xUnit architecture.

• zUnit is a xUnit instance for System z• Goal is to encourage the continuous integration and continuous testing methodology for System

COBOL Software Metrics

COBOL Software MetricsKey measurements of code complexity.

Basic metrics measures line and comment counts.

A number of well known metrics exist to measure codecohesion and cyclomatic complexity.

Metrics also support threshold values for 'rule style'reporting. When these values are exceeded refactoringand simplification of code is recommended.
