SAP SAPPHIRE and Teched 2011 Madrid, Tuesday – HANA, BI 4.x, Netweaver et al


My day started with informal discussions on future of BI products. Mobile BI is of course a no brainer next big thing.  Question is how is SAP going to tackle this? Webi is by far the most commonly touted mobile BI client. Xcelsius has the flash limitation on iOS, and even on Android – not all controls of Xcelsius work that well. Some time next year, when an Analysis client for mobile goes into ramp – there is an option to generate HTML5 layouts. If SAP does a good job on this, I would bet that this will start Xcelsius on its death march. Xcelsius is a great tool – but popular opinion is that it is not scalable for thousands of users. I have seen few hundreds use it, but not thousands. So I personally don’t know, and am willing to stand corrected. I will ask around more while I am here.

Next up is a question of how to best make dashboards etc out of ECC.  The big limiting factor in my opinion is that universes do not work on top of ABAP data dictionary. And if you go directly against the tables at SQL table – you will lose out on security, semantics and most probably will violate licensing agreements with SAP and the DB vendor.  The smart thing for SAP to do will be to allow universes to be built on ABAP data dictionary. This could single-handedly give an explosion to licenses sales for BOBJ. Any one listening  at SAP from sales side? To check out – I spoke with Adam Binnie, the GVP for BI. Many thanks to Andrea Kaufmann for finding some time for me with Adam.

There is no solution now or on roadmap to solve the flash compatibility issue. Adam said SAP team is checking on this in a research mode. It is not an easy problem to solve – there is a huge userbase for whom a disruptive solution might be painful to the extreme. Plus SAP has a limited option on a problem between Adobe and Apple. Nevertheless, SAP owes the world a solution for this somehow.

Although I feel SAP has not given Xcelsius the love it needs in near past, Adam thought otherwise. I think the disconnect essentially is that whatever is driving the product roadmap, probably is not very well integrated with the ecosystem. Adam said he will look into it, and that by end of the year he plans to put some concrete actions in place.

On the universe on top of ABAP data dictionary issue, it did not look like a priority for SAP. Adam thought this might be because multiple semantic layers (as in ABAP DDIC, and Common Semantic Layer from BOBJ both) might be against SAP’s design principles. Again, he agreed to check with his team and give me an update.

Of course no day passes in SAP land for me sans a thought on HANA.  if we fast forward to future – the big big thing is ECC running on HANA.  Is this the final frontier?  I am not too sure .  Over the last decade or two, SAP has made a lot of DML optimization already. Standard Business Suite behavior is to select once from database, hold it in memory – and then do all kinds of business logic in ABAP. So you could select a million records, filter it to hundred thousand with logic – then take it through Authorization checks to find what will pass, and end up with 10 records. If this logic is not rewritten completely – how much of benefit will SAP get by simply putting the tables in memory?  And think of the re-write – can you replace the ABAP logic with a bunch of database stored procedures ? Can you find a clever way of passing authorizations to hana at database level and not let ABAP do it? Will this mean HANA gets an ABAP interpreter? Too many complex issues to be solved to make it work efficiently.  So I raised this with SAP’s Deputy CTO Sethu Meenakshisundaram and a member of his team, Frank Samuel. Here is what they had to say.

SAP has a vision on how this would work going forward. The key to that is building a good foundational meta model in HANA that can represent the business objects in ABAP. Once DDIC, Security etc are modelled, then a standard API set can be used by ABAP and non-ABAP systems to do complex processing with HANA. But given the sheer amount of work, this will take some time to complete.  A consistent set of user friendly APIs is a tall ask for SAP in my opinion, based on what I have seen in past. Maybe they will do better this time.

Jon Reed brought up the question on multi-tenancy in the meeting. And I had posted this question on my blog earlier. I was quite pleased that Sethu had read my blog before hand. So according to Sethu, HANA is built as a multitenant model, except it is not used as such. Apparently, this is a simple thing for SAP to flip the switch. This is very different from what I have heard before, and I mentioned it to Sethu. He agrees that communication on HANA needs to improve from SAP’s side to minimize confusion. In any case, SAP not only needs to flip that switch, it should also build apps on HANA that are multi-tenant. And Vishal should mention it in his keynote to make sure the world is not confused, unlike what happened with ORACLE. BI OnDemand is a good start in this direction, and I expect more such things to come up in next few years

SAP has a grand vision on how the in-memory platform will help business. And i truly like what I heard. Sethu thinks Supply Chain is an area where SAP can do wonders with this, and I agree.  S&OP for example is an area where I have heard many customers request more of SAP. However, vision and execution needs to match.  SAP’s execution on HANA is not exactly stellar so far in my opinion, but I guess they will get there soon enough.

Next up was a meeting with Bjoern Goerke who is the Corporate Officer in charge of Technology and Innovation Platform at SAP. As always – a terrific meeting. I asked the same question on HANA multi-tenancy to him. His answer was more tentative than the one I got from Sethu – “not now, but we are working on it, and will get there soon”. While he agreed on the need for a good meta model on HANA and a framework for all the aspects like security, user provisioning etc – he could not give out any time frame for it. “One step at a time” was his answer. I respect that, although I think these are all things SAP should get out to the ecosystem as soon as they can. Technology should not be a huge limiting factor here – ABAP DDIC itself is stored in tables, and parts of this concept is already in use by other parts of SAP like BW replication etc.  SAP should do all they can to improve speed to get these things out of labs to the ecosystem. I asked Bjoern if BOBJ universes will be built on top of ABAP DDIC, and did not get a clear answer.

I did provide some feedback that HANA studio is not exactly a fine artwork, and got some assurance that it will improve constantly. SAP is moving all the developer studios to eclipse, which is the right thing to do. ABAP on eclipse is already available to see in the booth here. Apparently 7.3 Netweaver is doing great, and has 300+ live customers.  A lot more info on neo and ByD etc were discussed, and between Jon Reed and Dick Hirsch – I bet they will post their views after the meeting.

I would be terribly remiss if I did not mention this – Stacey Fish and Andrea Kaufmann from Mike Prosceno’s team deserve big time kudos. They are not only super helpful, they also try their best to give us as much information as possible so that we can form a more educated opinion before we blog. If they worked in my team, I would be writing performance bonus recommendations for them now. I cannot thank them enough

SAP Teched and SAPPHIRE 2011, Madrid – Monday


Fellow SAP mentor, Harald Reiter and I flew into Madrid on Monday morning from Phoenix on the same flight. Uneventful flight, and I managed to read about 400 pages of Steve Jobs biography. It is an impressive book, and I recommend it readily. We were a bit surprised at how long we have to walk from the flight to passport control counter. And we got a cab to go to  Hotel Silken Puerta América Madrid

 

A bit of an unusual hotel, I must say – looks very modern, unlike the regular Hilton and Marriott ones I get to stay during my work weeks in USA. Took me a few minutes to figure out how to make everything work – including curtains, lights and stuff.  Like many European hotels – the breakfast spread was awesome. We had a nice time catching up with the ever helpful Stacey Fish and Jon Reed at breakfast.

 

Another cab ride brought us to the convention center where innojam was in full swing. It was a lot of fun watching people do this, especially since I was spared the stress of another 30 hours of insomnia trying to get new technologies to work myself 🙂

 

While contestants were busy making final touches, Jon Reed and I got into a good discussion on HANA. I showed him some use cases on HANA that my Advanced Analytics team at IBM did.  Harald joined in too – and it was a fun discussion. Before coming to Madrid, I had put up my questions for SAP on HANA. https://andvijaysays.wordpress.com/2011/11/01/sapphirenow-2011-madrid-a-few-hana-questions-if-i-may/  After discussing with folks here at innojam – both SAP and non-SAP folks – my impression is that I am not the only one with these questions.

 

Rui Nougueira asked if I can stand in for a judge who could not make it to Madrid. It was quite an honor, and I readily agreed. My fellow judges were both senior SAP executives, and I was quite amazed with the content presented to us. It was webcasted live globally, and I believe a replay link will be provided in Teched site soon. First prize went to Carbon TNT – and that team did an amazing job with both technology and presentation.The prizes were given away by my colleague, since IBM loaned the HANA server to SAP for the event.

 

Post innojam – Harald and I caught up with Juergen Schmerder of SAP who is the man who runs all the systems for innojam. There isn’t a problem this man is not aware of, and he has been in SAP since 1999. Total straight shooter guy – and he gave us a lot of good information on HANA. I also spoke at length to Ruks Omar who is in the HANA marketing team.  Without going into all the details – I can just say this – some of the smartest people at SAP are trying to make HANA work perfectly on technical side. Where SAP absolutely needs to shore up is on talent to relate it to business problems, and a consistent methodology for HANA implementations.

 

Last event of the night was a mentor gathering organized by our chief herder Mark Finnern, and deputy herder Aslann.  It was great to catchup with all the mentors from Europe whom I don’t get to see often.

 

Dennis Howlett gave me a ride back to the hotel and I got a first hand taste of how Madrid traffic. I am glad I did not rent a car here. Tuesday is an action packed day with many nice meetings on the schedule. Looking forward to it

 

 


 

 

Thoughts on SAP Outsourcing, Part 2 – the Devil’s Polygon


Now that I have walked down the memory lane, this time around let me share some thoughts on what earned outsourcing a bit of bad reputation. Again, this is all just my personal view and not that of past or present employers. Outsourcing is not a perfect world at all – and the ill will it generates can be attributed to a devil’s polygon ( taking a  clue from my friend Mike Krigsman  who is famous for Devil’s triangle). Many players are involved and they all have different POVs.  Since I have not worked from the customer side – I don’t claim to be totally objective in my thoughts. But for what it is worth, here you go.

1. Pushing people through the career hierarchy before they had a chance to make mistakes and learn at the lower rungs is a common scenario in this high demand market. If a developer makes a mistake, it can usually be corrected without too much trouble. And then the developer learns what not to do, how to react when things go wrong, how to explain to client and management etc while limiting the risk. If this developer became a team lead or a PM too quickly, and goes through the learning process with errors at that level – chances are it won’t end well. Bad managers are the biggest reason in my opinion on why outsourcing earned criticism.

2. Lack of understanding from customers on what they bought, also ranks up there on top. Before outsourcing, a customer would have had an inhouse team doing everything. And since the IT team sits next door and goes to lunch a beers with you, there is generally a good camaraderie. If you make a call to your friend and ask her to add a field to a report, she will probably oblige occasionally without a formal process. She might also offer some support over phone if it is not in office hours for sake of friendship. When outsourcing happens – you are already stressed out that your friend is not in that job anymore, and you need to follow a rigid process to get things done. No one told you that for cost reasons, your management only bought 8 hours of a day of support. So when that last minute change is needed on Friday at 4 PM, chances are that it won’t get done before you go home.

The funny part is that the same people as consumers are totally fine if this happens to them with say a cell phone company. You raise a ticket, wait for it to be fixed and you cannot call for updates every minute. For days at length, you will be forced to see “in progress” as status on their website. Yet we get stressed out if the same thing happens when our own employers outsourced to another provider.

My biggest gripe with how companies buy outsourcing services is the lack of due diligence on customer’s part on what they need to buy to do business as usual. If the service provider tries to educate the customer – more often than not, it will be percieved as “hard selling”.  I am not letting the outsourcing companies off the hook either – they need to better explain what is in the basket and what is not.

3. Economic differences are a big contributor  too. When USA and Europe are going through a bad economy, and we lose jobs to Asian countries – we of course will feel bad. What we occasionally forget is that it is a direct result of how capitalism encourages competition. If local workforce can come up with a model where they can be competitive, there is a fair chance that a lot of these jobs will stay here. We cannot take a stance that “I will continue to do what I have done all my life, and I expect to get same or better pay, and I will refuse to believe my skills have become commoditized.”. Apples to Apples – it will be difficult for a person in US to compete on a wage basis to a person in India or China. However, if the game is changed – say the person in US can form a team that supports multiple clients, and provide better service – there is no reason why this should not work out well.

4. Social differences are better now from the time I started in SAP area. I have sat in many meetings in my first few years in America and Europe and listened first hand to “oh this is not complex, we can probably throw it to the Indians” and “they are just ABAPers” and “do you go to office in India on horseback?” and many others that were so rude, that I cannot bring myself to write it here. It took a few years for me and many other colleagues from India to feel that we are part of the team too. This has vastly improved with time. When you feel crappy on the social side, it is pretty hard to concentrate on work fully. Although I felt terrible at the time , I also realized later that my American and European colleagues and clients were not trying to be intentionally rude. They had never been to India before, and they found it incredibly hard to understand my thick accent and long name. They also did not know why their employers got Indians to join the team in the first place. A lot of this frustration on both sides could have been eliminated or at least reduced if outsourcing companies and clients who bought their services communicated the plan clearly and did so right upfront, and not after every one got wound up.

I will also tell you a rather funny story. A good friend of mine – also an ABAPer from India – started in US working for a client of mine. I was working in a US based big SI, and he for an Indian firm. Client used to treat consultants from my employer kind of on par with their own staff, and we would get invited to nice dinners and ball games and so on. My friend on the other hand never got this opportunity, and did not know this was going on. A year later, he joined my employer and started seeing the difference in how he was treated by the client. And when we went live, the development lead from the client congratulated my friend saying “this guy from so and so company wrote a brilliant application, and our users love it. It totally validated my reason of hiring this SI to help us be successful”. We all cheered big time, but the funny part is that this terrific app was written by my friend way before he joined my employer. He never told the client manager, but till date – every time I talk to him, we joke about this.

5. In a dog-eat-dog world, people snipe quickly to protect turf. Having worked for very small and extremely big employers, I can say with some confidence that neither side has earned the right of  “holier than thou” . I have been sent in to rescue projects screwed up by cowboy developers from small SIs or independents . I have also worked in very small shops where we were appalled by the work done by the SI who put in the SAP solution. In general – big SIs get more of a bad reputation in these cases because they have a recognized brand. People who are independent now or work for small shops – most of them had a history of working at a larger shop before where they gained experience and became the big expert. So it is not as if when they moved out, the past shop became pretty bad. People and companies protect turf – and customers know that only too well by now.

6. People forget that SAP product was not this mature in the mid 90’s. A lot of work that looks terrible when we look back were clever work arounds that were done to make SAP work on those releases. When such a system gets outsourced for support, and complex problems arise – they might not have elegant solutions. Short of reimplementing SAP, usually the only way is to apply even more band aids. But when this is looked up on from outside, it looks terrible and the fault is attributed immediately to poor skills of the people supporting it.

7. The factory model used by many outsourcing companies get a lot of flak – usually from people who do not have the ability or scale to do that. Factory model works – if it did not, many big businesses would have closed shop by now. Obviously, this model needs a revamp since the model has not kept up with advances in technology, especially on infrastructure side. The reason it still survives is because – despite all that is bad with it, it gets the job done cheaper in most cases (when it does not for a few cases, it gets more bad press than the many times it works). Factory model works only if it is implemented properly, with the associated change management. In several cases, the change management gets kicked to the curbside, and then it goes downhill pretty quickly. If all parties know how the model is supposed to work, and commit to it – it works like a charm. When you skimp on some parts, it fails. Outsourcing companies and clients need to do a better job in change management, and educating the clients and their own staff onsite on what it takes to get it done successfully.

8. Talent retention is an issue for customers as well as outsourcing companies. However, outsourcing companies have scale in their favor. This is their bread and butter business and they have a better ability of sourcing and retaining talent. However, there are things that are not in anyone’s control – like the current restrictions on work visas in US. A lot of plans that were put in place long term for outsourcing projects, now need to be revisited, and I expect some outsourcing horror stories to surface. From the perspective of local work force, this is great – because it provides a window of opportunity to get good jobs. The current demand and supply situation is kind of weird – there are lot of unfilled seats in technology jobs, and there aren’t enough skilled people to take it. This skill mismatch is a deeper problem that needs a re-engineering of fundamental aspects like education reform etc. It will take time to fix.

9. As an inhouse expert in SAP – it is pretty common that employees gain exposure to multiple skills. I have many friends who can do ABAP and SD configuration and BW. This is not a model that outsourcing companies have actively worked on in my experience. In traditional outsourcing models, due to price, nature of work etc – ABAPers generally do only ABAP, and BW folks only do BW and so on.  A small percentage will get cross trained , but they are the exception. However, this part does not get recognized when these people are pulled into outsourcing projects. I have heard hundreds of requests from customers on “why can’t you find me an SD consultant who can also do BW reporting? Joe , who used to work here, could do all of that plus some ABAP” .  It is not easy to find a like-for-like replacement for Joe at the price a customer is willing to pay for that service.

10. The most common complaint you would hear probably is “these people are still stuck in ancient ABAP coding ways. They don’t do OO ABAP, they don’t know what web services are…are they living in a cave?”.  Most outsourcing shops – atleast the good ones – have good training programs that train people in latest and greatest technologies. However, not everyone is sent for that training. It is expensive to train people, and companies won’t invest in training tens of thousands of people unless they see a demand for the specific skill, and a premium for it. SAP is generally very backward compatible  – so several customers have decided to just move on with that is already built, and just “keep the lights on”.  They will try new things for new projects – but are generally hesitant to fix existing ones. As a result, the people supporting these projects have to remain in the old way of doing things. We should also understand that in most cases – time to develop a solution trumps everything else.  So if there is a bug in a program, the biggest requirement is to fix it and get it back to working state. In the hurry to fix it, more band aids get applied.  Unless a customer is willing to spend money on cleaning up existing mess, this problem will only continue to get worse.  In current economic scenario – I doubt how many will open their wallets to do that in near future.

It is hard to keep this series in a structured format with so many things rushing to my mind. But I will try my best to get it more organized as I move forward. I am typing this from the plane on my way to work, and lack of good coffee has to take some blame for my random thoughts too 🙂
