ERP Buyers Guide
http://post.technologyevaluation.com/t/180998/19677306/17511/2/?560a3889=VEVDIDIwMTUgRVJQIGZvciBEaXNjcmV0ZSBNYW51ZmFjdHVyaW5nIEJ1eWVyJ3MgR3VpZGU%3d&3b64e84d=X19uZXdzbGV0dGVyX2RhaWx5X2Vu&3b64e84d=X19uZXdzbGV0dGVyX2RhaWx5X2Vu&b0c7069d=MjM4NDEzOA%3d%3d&fb8dc108=cndoZWVsZXJAYXJ0aWZhY3Qtc29mdHdhcmUuY29t&x=3c8d597c
is a link to an interesting whitepaper from TEC (Gartner competitor)
discussing the main ERP solutions that they follow.
The big trend that they identify is a move to more functional user
interfaces that actually help users make sense of the data and find what
they want quickly and do that in a way that is familiar to ERP users
(Spreadsheets model).
They talk about automatic search where the user can type information
into any field (phone number, first name, company name and have the
system show up potential matches without having to go to a search
screen. This is what people who use email or web browsers expect
computers to be able to do.
They expect that an ERP can be customized by each end-user to meet the
needs of their job function and their aesthetic needs and that color be
used effectively to highlight important information on screens.
They also discuss the trend towards strong analytics.
It includes screenshots from the top ERP solutions so it is easy to see
what product evaluation analysts are looking for.
Integration of Social Networking is coming to ERP as well.
This should be carefully read before any attempt is made to get Gartner
to evaluate OFBiz since it will give some indication about what they are
going to expect when they open the demo and how they will approach the
UI and analytics capabilities and data presentation.
Around page 18 there is a checklist of the functionality in 11 major
areas that is covered by the ERP solutions (20 covered) that they
consider important for Discrete Manufacturing situations.
Big discussion on the business case for CPQ and how this is becoming
important in ERP selection.
There are companion articles about ERP for Process Industries and other
applications that can be downloaded.

Too far past my pay-grade!
This is more for the people working on the long-term development plans
and the marketing position of OFBiz.
Not every competitor has all of the ideas incorporated into their products.
Not every idea is going have an ROI that the OFBiz community will find
compelling but I thought that it was something worth reading for anyone
who is looking at the future of OFBiz.
If there is anyone contemplating UI changes or addition of new modules,
it is interesting.
It is not overly detailed and the discussion is about trends rather than
specific product implementations.
It also has some slides about where the customers are spending money and
what areas are getting $$$ attention by ERP users.
The feature checklist might be something that we might want to use as a
base for some pages in the web site.
It certainly gives a way to group functionality into a reasonable set of
categories that fit on 1 page and gives a scale that can be used to
indicate how extensively OFBiz supports the requirements. Easy to
compare the other companies using the TEC guide.
I am not sure how different Gartner's breakdown is.

Then as I proposed a tool like Solr seems appropriate. But this means also a lot of work to integrate.

Yes this is actually the problem. Not everybody can afford such load and actually need the feature.

It's a bit like bid data. It greats to have when you need it, but not everybody really needs it and can afford what it entails.

Re: ERP Buyers Guide

I think that they are showing search results as the user types and the
ERP does not care what field you are entering.
If you start typing in the postal code field it will display everyone
whose postal code matches what you have typed so far.
When you stop typing, you can select the party that you are interested
in from the search results on the screen.
If you start with a phone number or last name or whatever, the effect is
the same.
It clearly places a load on some computer(server or browser) and the
balance between bandwidth, server processing and user convenience is
constantly changing.
The dropdown filtering is a good start but they are carrying the process
one step further.

I did not read yet.
When we standardized javascript in OFBiz, by replacing all other javascript frameworks and APIs by jQuery, there have been a specific effort around
lookups and we implemented the auto-complete feature inside them (actually the js standardization came from this effort, which was initially done on
the calendar where we began to replace pop-ups by js-layers). Auto-complete is just the feature you explain above. Of course limited, it's not a
search engine, the set is constrained. In theory, we could have something much more powerful based on Solr for instance. But I'm not sure we will ever
see that in OFBiz...
BTW, during the jQuery effort, I improved the Price Rules and Promo Rules screens, using dependent dropdowns I then introduced (you would have to use
R09.04 to see how it was before). I even made recently an effort in the Product Promo Rules screen to use auto-complete lookups instead of simple inputs
http://svn.apache.org/viewvc/ofbiz/trunk/applications/product/webapp/catalog/promo/EditProductPromoRules.ftl?r1=1653938&r2=1653937&pathrev=1653938
I believe there are still inputs we could replace by auto-complete lookups. An effort which would be worth to do would be to take an inventory of
those. We could then replace them...
