  • Ways IT Teams Work: Federation Unified by Process

    This is part two of a multi-part series on how teams are organized and how they work together within a set of conventions and constraints. This post describes an organization that creates products and offerings with members that work simultaneously on multiple projects. A well-defined process, not very different from a traditional systems development life cycle (SDLC), guides this federated team.

    Ways IT Teams Work: Hierarchy Aligns With Operations

    This week, I’m starting a multi-part series on how teams are organized and how they work together within a set of conventions and constraints. I am writing this series from my own experience as a team member at different parts of my career.

    sig·nif·i·cance – IT Disciplines

    This week, I’m continuing the series on significance (the quality of being worthy of attention or importance). For this post, I want to focus on the well-formed and innovative ways that humans manage enterprise systems, network and applications. I will also survey the notion of a comprehensive list of all services provided by IT, an inventory of enterprise capabilities.

    sig·nif·i·cance – Installation of Products, Enhancements and Fixes

    This week, I’m continuing the series on significance (the quality of being worthy of attention or importance). For this post, I want to focus on a remarkable z/OS utility called System Modification Program/Extended (SMP/E).

    sig·nif·i·cance – Workload Management

    This week, I am continuing this series on significance (the quality of being worthy of attention or importance). For this post, I want to focus on a component of z/OS called Workload Manager (WLM). It handles the varied and diverse work that runs in a z/OS system giving the individual jobs, started tasks and time sharing option (TSO) users the system priority desired by the business that’s running the software.

    sig·nif·i·cance – System Management Facility

    This week, I am continuing this series on significance (the quality of being worthy of attention or importance). For this post, I want to focus on a component of z/OS called SMF. As a new application developer, I had no exposure to SMF. It was something developers didn’t know about because we were focused on other things like using COBOL and VSAM to code a solution to the specs given to us by our analyst. Later, when I became a system programmer trainee, I became aware of the enormous significance of SMF.

    sig·nif·i·cance – CICS and IMS as Early Real-Time Middleware

    Last week, I wrote about how middleware came about because of the emergence of distributed computing systems. I wrote that these new systems created a need for certain types of software that had not existed before or existed mainly for internal use. Middleware software has roots in software that was developed for centralized computing for both batch and online processing. This week I focus on the real-time roots of modern middleware.

    sig·nif·i·cance – JES as Early Batch Middleware

    It’s generally accepted that modern middleware came about because of the emergence of distributed computing systems. These new systems created a need for certain types of software that hadn’t existed before or existed mainly for internal use. This new software came about to support client-server computing. However, modern middleware software has firm roots in software that was developed for centralized computing.

    sig·nif·i·cance – z/OS

    This week, I am continuing this series on significance (the quality of being worthy of attention or importance). For this post, I want to focus on z/OS, an OS that’s been used for more that 15 years and has it roots in predecessors from OS/390, MVS/ESA, MVS/SP, OS/VS 2, OS/VS1 and OS/360 (which first shipped in 1965). z/OS has been more than 50 years in the making with a huge investment of human computing resources and large and varied input from its users over the decades.
