Well, they say you can't teach an old dog new tricks. Things that have existed for years
and decades will simply continue to exist. Why do something new or change?
So I am a guy who has worked in IBM for 36 years, but has changed jobs and
positions every 5 years or so. I guess I have job hopped within the same business
and been luckier than most to be able to do it. The one thing that has been pretty
constant in all of this is that the z platform was here before I started with IBM and
will be here long after I leave IBM. I guess you can call it a survivor even though
there seems to be articles every year that are touting its impending doom. I think like
my job hopping, you pick up new skills, address new challenges and adapt to
keeping yourself valuable to the business. It would seem to me that the z has done
the same and continues to adapt and change, but keeps the same value proposal
that major business requires as it moves through time.
One of the interesting ideas that changing times is creating is a big stir for the z and all z
users. Is the green screen the only presentation service that is required or that
will ever be required for the z subject matter experts? This has created different
opinions from many of the businesses I talk with as well as operations folks,
tooling support folks and others in IT that are starting to see alternatives show
up on the doorstep, regardless of whether it is needed or not. As far as I have read,
a lot of the details or say the imperative of alternatives to green screens
would be that all the kids (I myself am far from a kid) or people entering the IT world
are from a gaming background or are so trained in web browsers and pop ups that
the only way to keep the business going is to change the old technologies to
adapt or adopt to make IT support and the z platform viable and to have a way to
bring new talent into the IT business.
In particular, the z stands out in this because of the vast green screens being
used today and the idea that with a greying workforce (that could be me), there
is a critical shortage of upcoming people who would find it appealing enough
to work on z systems or subsystems if it were just that plain old green screen.
That to me is pretty interesting as part of a product manager team with
Tivoli and OMEGAMON and and discussing System Management requirements
with customers because I think that down the road, there will be requirements
where both the green screen and the vast arrays of GUIs with web 2.0 and beyond
will have a pretty dramatic impact on the IT folks who support the z and z subsystems.
I think the idea of having a reach and range of information about how IT systems
are working or not working will create what I call a funnel system that works
in several ways.
A basic premise is that if you want to manage the business effectively and with
an eye on the TCO of all the running technologies deployed, you integrate an
end-to-end perspective, and ensure that any bump in the night generates an
event/alert and that gets sent to a focal point where someone or some automation
routine is running. This seems to be a standard operation within a mature systems
management IT shop. This data is filtered, reduced and hopefully has
a meaningful message when it gets to the end of the funnel and someone looks at it.
Since we are talking and end-to-end view and consolidation of this information....
Should it be a green screen? A MCS for the enterprise?
I think that the diverse information being received precludes that from ever becoming
a reality in IT. As companies staff help desks and customer service centers, it would
seem that graphics and Web GUIs are taking the predominant role with all sorts of
capabilies to sort, or display and relate impacts on the business.
In fact, this area keeps changing, it seems, every 6 months with new internet technologies
being introduced all the time. There are different use cases and personas using this
web technology that are the first line of awareness even if the trouble ticket is cut
automatically when something goes bump in the night. The event shows up at this
integrated web/portal based GUI orin some business several portals/GUIs where
the different personas might have a different IT process to work on. So, I think the case
of only having this in a green screen has passed in time.
Now the issue is if the bump in the night happened on the z or a z subsystem...haste
and speed to resolve are a priority because of the potential loss of $$. So if the bump
in the night is shown in a nice graphical web based portal, and we all know that web
response time is not what you call as dynamic as a green screen, it creates the dilemma
that IT people are discussing. Is there only one choice here or multiple?
Is it better to have a wide range of data available to view or is it better that we need a
quick reach into the z system and subsystems with speed?
Next up Funneling out..
