Why Web measurements? The Series.

December 8th, 2008 by smp | Comments | Filed in Uncategorized

In my life as a consultant, I often discuss What Web performance data means and how to interpret it to solve problems. Solving the problems is, however, inherently based on whether the data that is collected is meaningful. In trying to find data that is meaningful, we have found that there are four categories that Web performance measurements fall into: Customer Generation, Customer Retention, Business Operations, and Technical Operations.

Why Web Measurements? Part III: Business Operations

December 5th, 2008 by smp | Comments | Filed in The Web, Web Performance, WebPerformance.Org, Work

In the Customer Generation and Customer Retention articles of this series, the focus was on Web performance measurements designed to serve an audience outside of your organization. Starting with Business Operations, the focus shifts toward the use of Web performance measurements inside your organization.

Why Business Operations?

When I was initially developing these ideas with my colleague Jean Campbell, the idea was to call this section Reporting and Quality of Service. What we found was that this didn’t completely encompass all of the ideas that fall under these measurements. The question became: which part of the organization do reporting and QoS measurements serve?

What was clear was these were the metrics that reported on the health of the Web service to management and the company as a whole. This was the measurement data that the line of business tied to revenue and analytics data to get a true picture of the health of the online business.

What are you measuring?

Measurements for business operations need to capture the key metrics that are critical for making informed business decisions.

  • How do we compare to our competitors?
  • Are we close to breaching our SLAs?
  • Are the third-parties we use close to breaching their SLAs?
  • What parts of the site affect performance / user experience the most so we can set priorities?
  • How does Web performance correlate with all the other data we use in our online business?

Every company will use different measures to capture this information, and correlate the data in different ways. The key is that you do use it to understand how Web performance ties into the line of business.

How often do I look at it?

Well, honestly, most people who work in business operations only need to examine Web performance once a day in a summary business KPI report (your company has a useful daily KPI report that everyone understands and uses, right?), and in greater detail at weekly and monthly management meetings.

The goal of the people examining business operations data is not to solve the technical problems that are being encountered, but to understand how the performance of their site affects the general business health of the company, and how it plays in the competitive marketplace.

What metrics do I need?

Business operations teams need to understand

  • End-to-end response time for measured business processes
  • Page-level response times for measured business processes
  • Success rate of the transaction during the measurement period
  • How third-parties are affecting performance
  • How Web analytics and Web performance relate
  • How different regions are affected by performance
  • How does performance look from the customer ISPs and desktops

Detailed technical data is lost on these people. It is their role to take all of the data they have, and present a picture of the application as it affects the business, and discuss challenges that they face at a technical level in terms of how they affect the business.

Summary

For people who work at an extremely detailed level with Web measurement data (the topic for the next part of this series), Business Operations metrics seem light, fluffy, and often meaningless. But these metrics serve a distinct audience: the people who run the company. Frankly, if the senior business leaders at an organization are worried on a daily basis about the minute technical details taht go into troubleshooting and diagnosing performance issues, I would be concerned.

The objective of Business Operations measurements is to convey the health of the Web systems that support the business, and correlate that health with other KPIs used by the management team.

Why Web Measurements? Part II: Customer Retention

December 2nd, 2008 by smp | Comments | Filed in The Web, Web Performance, WebPerformance.Org, Work

In the first part of this series, using Web performance measurements to generate new customers was the topic. This article focuses on using the same data to keep the customers you have, and make them believe in the value of your service.

Proving the Point

Getting a customer is the exciting and glamorous work. Resources are often drawn from far and wide in an organization to win over a prospect and make them a customer.

Once the deal is done, the day-to-day business of making the customer believe that they are getting what they paid for is the job of the ongoing benchmarking measurements. CDNs and third-party services need to prove that they are delivering the goods, and this can only be done by an agreed upon measurement metric.

Some people leap right into an SLA / SLO discussion. As a Web performance professional, I can tell you that there are few SLAs that are effective, and ever fewer that are enforceable.

Start with what you can prove. Was the performance that was shown me during the pre-sales process a fluke, or does it represent the true level of service that I am getting for my money?

Measure Often and Everywhere

The Web performance world has become addicted to the relatively clean and predictable measurements that originate from high-quality backbone measurement locations. This perspective can provide an slightly unrealistic view of the Web world.

How many times have you heard from the people around you about site X (maybe this is your site) behaving badly or unpredictably from home connections? Why, when you examine the Web performance data from the backbone, doesn’t this show up?

Web connections to the home are unpredicatble, unregulated, and have no QoS target. It is definitely best effort. This is especially true in the US, where there is no incentive (some would say that there is a barrier) to delivering the best quality performance to the home. But that is where the money is.

As a service provider, you better be willing to show that your service is able to surmount the obstacles and deliver Web performance advantages at the Last Mile and the Backbone.

Don’t ever base SLAs on Last Mile data - this is Web performance insanity. But be ready to prove that you can deliver high quality performance everywhere.

Show me the data

As a customer of your service, I expect you to show me the measurement that you’re are collecting. I expect you to be honest with me when you encounter a problem. I do not want to hear/see your finger-pointing, especially when you try and push the blame for any performance issues back to me.

As a service provider, you live and die by the Web performance data. And if you see something in the data, not related to your business, but that could make my site faster and better, tell me about it.

Remember that partnership you sold me on during the Customer Generation phase? Show it to me now. If you help me get better, this will be added to plus column on the decision chart at renewal time, when your competitor comes knocking on my door with a lower price and Web performance data that shows how much you suck.

Shit Happens. Fess up.

The beauty of Web performance measurement is that your customers can replicate exactly the same measurements that you run on their behalf. And, they may actually measure things that you hadn’t thought about.

And sure as shooting, they will show up at a meeting with your team one day with data that shows that your service FUBAR‘d on a massive scale.

It’s the Internet. Bad shit happens on the Internet. I’ve seen it.

If you can show them that you know about the problem, explain what caused it, how you resolved it, and how you are working to prevent it, good.

Better: Call them when the shit happens. Let them know that you know about the problem and that you have a crack team of Web performance commandos deployed worldwide to resolve the problem in non-relativistic time. Blog it. Tweet it. Put a big ‘ol email in their inbox. Call your pimary contact, and your secondary contact, and your tertiary contact.

Fess up. You can only hide so much before your customers start talking. And the last thing your want prospects seeing is your existing customers talking smack about your service.

Summary

Web performance measurement doesn’t go away the second you close the deal. In fact, the process has only just begun. It is a crazy, competitive world out there. Be prepared to show that you’re the best and that you aren’t perfect every single day.

Why Web Measurements? Part I: Customer Generation

December 1st, 2008 by smp | Comments | Filed in GrabPERF, The Web, Web Performance, WebPerformance.Org

Introduction to the Series

This is the first of a four-part series focusing on the reasons why companies measure their Web performance. This perspective is substantially different than ones posited by others in the field as they focus on the meat and potatoes reasons, rather than the sometimes more difficult to imagine future effects that measurement will bring.

Reason One: Customer Generation

It is critical that a company be able to show that their Web services are superior to others, especially in the third-party services and delivery sectors of the Web. In this area, Web performance measurement is key to demonstrating the value and advantage of a service versus the option of self-delivering or using another competitor’s service.

Comparative benchmarking that clearly demonstrates the performance of each of the competitive services in the geographic regions that are of greatest interest to the prospect is key to these Web performance measurements. To achieve truly competitive benchmarks and prove the value of a service, measurements must be realistic and flexible.

In the CDN field, a one object fits all approach is no longer valid. CDNs are responsible for delivering not just images or static objects, but may also host an entire application on their edge servers, serving both HTTP and HTTPS content. In other cases, the application may not be hosted at the edge, but the edge server may act a s a proxy for the application, using advancing routing algorithms to deliver the visitor the requested dynamic content more quickly (in theory) than the origin server alone.

This complex range of services means that a CDN has to be willing to demonstrate effective and efficient service delivery before the sale is complete. A CDN has to be willing to expose their system not just to the backbone-based measurements offered in a traditional customer generation process, but to take measurements from the real-user perspective.

Ad-providers have to be willing to show that their service does not affect the overall performance of the site they are trying to place their content on. Web analytics firms face the same challenge. Web analytics firms have one advantage: if their object doesn’t load properly, it may not effect the visitor experience. However, neither ad-providers nor Web-analytics providers can hide frow Web measurement collection methods that show all of the bling and the blemishes.

Using Web performance measurements to generate customers is a way that a firm can clearly show that they have faith enough in their service to openly compare it to other providers and to the status quo.

But woe be the firm who uses Web performance metrics in a way that tries to show only their good side. Prospects become former prospects very quickly if a firm using Web performance data to generate new business is found to be gaming the system to their advantage. And it will happen.

Customer Generation is a key method that Web performance measurements are used by firms to clearly show how their service is superior to what a prospect currently has, or is also considering. However, this method does come with substantial caveats, including

  • The need to measure what is relevant
  • The need to measure from where the prospect has the greatest interest
  • The need to consider that gaming the system to show advantage will cost a firm in the end.
