Agile Outsourcing
The problem
Outsourcing is a "special" animal. Typically the idea is to save cost by letting a service provider execute work. The saving cost happens because the service provider is supposed to be able to perform this actions at scale. Increasingly outsourcing deals are motivated by a skill squeeze. So instead of maintaining in-house expertise, rely on the vendors to keep the light on.This is where the trouble starts. Negotiations on outsourcing contracts revolves around price (drive it down) and the SLA (add as many 9 behind the comma as possible). The single outcome of such contracts is extreme risk aversion. For illustration here is the impact of SLA levels :
SLA | Total annual Downtime |
---|---|
98% | 7 days, 6h, 12min |
99% | 3 days, 15h, 36min |
99.9% | 8h, 45min, 36sec |
99.99% | 52min, 34sec |
99.999% | 5min, 16sec |
99.9999% | 32 sec |
Looking at some of the figures (I can't share) I would claim that short of highly parallel (and expensive) transaction system anything above 99.9% is wishful thinking. That doesn't deter negotiators to aim for a "look how many 9th I got" trophy. (While the Buddha reminds us: one cause of suffering is to close your eyes to reality). Expensive SLA violation clauses let outsourcers freeze all system, since any change (read: patches, upgrades, enhancements) is rightly identified as grave risk (to the profits).
So all sorts of processes and checks get implemented to vet any change request and in practise avoid them.
This usually leads to a lot of bureaucracy and glacial progress. As a result discontent, especially on the use of non-transactional system grows: Stuff like outdated eMail clients, lack of mobile support etc. etc.
The relation between oursourcer and oursourcee grows, inevitably, challenging over time. Does it have to be that way?
Some fresh thinking
Just move to cloud might not be the answer (or everybody would be there, it's such a nice place). So what could be done? Here are some thoughts:- Kiss goodby the wholesale SLA agreement. Classify systems based on business impact. A booking system for an airline surly deserves three nines (I doubt that four would make sense), while a website can live with one nine (as long as it distributed over the year)
- Take a page from the PaaS offerings: each element of the environment has a measurement and a price. So the outsourcing provider can offer ala card services instead of freezing the environment. A catalogue entry could be "Running a current and patched DB/2", another entry could be "Run a legacy IIS, version xx"
- Customer and provider would agree on an annual catalogue value, based on the starting environment and any known plan at the time
- The catalogue would allow to decommission unneeded system and replace them with successors without much hassle (out with PHP, in with node.js)
- Automate, Automate, Automate - An outsourcer without DevOps (Puppet, Chef and tight monitoring) didn't get the 2017 message
- Transparency: Running systems over processes, Customer satisfaction over unrealistic SLA, Automation over documentation (I hear the howling), Repeatable procedures over locked down environments
