利用统一用户视图增加用户粘度

   统一的用户视图这个概念现在在数据分析和挖掘领域尤其显得重要,能给用户分层,用户忠诚度,一对一营销等项目的提供前所未有的分析空间,越来越多的企业开始重视利用EDW来对用户做全方位的分析,BEST BUY就是其中之一。

   BEST BUY 是全球最大的家用电器和电子产品的零售和分销及服务集团。 BEST BUY 企业集团包括 BEST BUY 零售、音乐之苑集团、未来商场公司、 Magnolia Hi-Fi 、以及热线娱乐公司。 BEST BUY 在北美同行业中处于领先地位,着眼于企业展望、使命和价值观。 BEST BUY 名列全美财富 200 强第 131 位,全球 500 强企业第 247 位。

  ”Intelligent Enterprise”杂志最新一期上有BEST BUY 公司Customer Insight部门资深总监Matt Smith的一篇访谈,让我们来看看BEST BUY是怎么利用统一用户视图来提高客户粘度的。

  Why is Best Buy moving into cross-channel analysis?

When you look at some of the traditional tools, either Web analytics or BI tools, they tend to be pointed very much at the business. It’s about counting widgets or numbers of clicks and understanding behavior only in an aggregate form ” how many bought X product, reported Y problem through the call center or looked at Z page on the Web site. The customer insight team is focused on beginning that analysis from the perspective of an individual consumer. A few years ago we built a customer database that houses [online and offline] transactional data at a consumer level. In the last couple of years we’ve started to bring non-transactional data into those databases.

Can you describe the data warehousing environment?

We have two primary data warehouses that sit in our IT space. One is engineered for rapid response and cycle time and it’s meant to deliver customer information back to the point of sale in the stores very rapidly. The other customer database is engineered for much deeper queries and analytics. Both of these databases were originally built on Oracle. We’ve begun using Teradata in other places in the enterprise and we’re examining whether there’s value in transitioning those databases to Teradata. The second database has somewhere around a decade’s worth of transactional data combined with third-party information. We’re beginning to link non-transactional data into these stores as well. The two databases are also connected; we do some model scoring in the deeper analytics database and those scores out to the enterprise customer database.

What kinds of non-transactional data are you adding to the mix?

The first step we took [two years ago] was to connect the transactional data across channels, including Web site transaction data and in-store point-of-sale data. That lets us see customers who are single-channel and multi-channels, and we know how they behave across channels. We’ve added clickstream data for those who log in at the site or who use their Reward Zone number, and we can begin to understand that behavior. We’re just now working through call center data as well, so if you’ve called Best Buy for service or a problem with a product or if you called to check on your Reward Zone account, we’re just beginning to merge that data with our transactional data.

What will you learn by bringing all this information together?

Number one, we know from some of our early work that some of our best customers tend to be multi-channel customers. They have a large number of interactions with the brand on an annual basis, and the idea is to create a well-rounded view of the consumer. We also know that our best customers drive our business. As we’ve exposed Best Buy to more and more consumers, we’re quickly moving out of the customer acquisition game and into relationship building, so understanding the health of the customer relationship across channels is crucial.

What tools do you have in place to perform cross-channel analysis?

There are two pieces to that. One piece is how you listen to customers, and that’s what these databases are doing. The second piece is what you do with that insight and how you talk to customers. We use Visual Sciences [formerly WebSideStory] to do Web analytics and we also use its visualization tools to do analytics [across channels]. We use Unica’s Affinium software to understand how to talk to customers. We’ll set up a series of business rules around particular behaviors and the idea is to respond to customers with particular messages based on the behaviors we’re seeing.

For example, if we see that you’re doing research online in the home theater space or we see that you’ve gone to a store and made purchases in the home theater space, we want to begin tailoring our messages to you to help you build the best home theater experience.

How are you delivering those messages?

Right now we’re using e-mail and direct mail. As we continue to redesign the Web site and open up more screen space, individual customer personalization on the Web will become a bigger tool for us. Where we think this will really have power is if we can inform the blue-shirt sales associates [in the store] with the same data we’re using to make ink and pixels smarter.

How far out is that capability?

That’s a very complicated strategy. We’ve already begun to do it in small ways, but it won’t be fully integrated for a couple of years.

Just what would you communicate to the sales associates?

We’ve built robust personas for our customer segments, and our sales teams understand the attitudes and motivations of those customers very well. We’ve also begun to think about the way we sell product in a different way as a result of some of this behavioral work. A couple of year ago, if you came in to buy a digital camera, we thought about you as buying a digital camera. Now we understand, from watching customer behavior, that what you’re really doing is trying to build a solution around sharing memories. That expands the relationship beyond just that product to a variety of products that will help you capture, edit, archive and share memories, such as editing software, printers, memory cards, accessories or off-site digital archival. It extends the way you think about what the customer is tying to do. We can take what we learn and apply that to our training for the blue shirts.

Best Buy’s customer personas are well know, but can you share some examples?

“Jill” is the affluent suburban soccer mom archetype. Jill is very busy and very concerned about how her family consumes technology. She hasn’t particularly embraced Best Buy as one of her favorite shopping destinations, but she understands that it’s important for her family, so we help her navigate the experience. Another persona is “Barry,” who is an affluent suburban male who enjoys home electronics and complete solutions. Because he’s affluent, Barry tends to buy higher-end products.

We’ve thought about Barry and Jill for a long time, but now we can think about how to help them with more complete solutions. In the future, we’d like to be able to deliver a very particular message to a particular Jill that reflects where she is in filling out a solutions bundle. We would understand the context of the products she has already purchased and we’d know which product we have that would help her extend the solutions and which ones will work with the products she already owns. That’s where you can get very personal. It’s easier to do that through the mail and online right now, but it’s much more challenging to deliver that to a sales associate in the store, so that’s the piece that we’re working on.

What kinds of personalized messages are you already sending via e-mail and direct mail?

If you bought a home theater solution from us with a plasma TV and some other products, you might get a direct mailing on home theater surround sound, clean power supply or universal remote controls. If you were to buy a notebook computer, you might get a piece on our Geek Squad brand talking about home networking options or flat-panel displays. We can tailor the message based on customer and geographic segment and the customer’s value to the brand.

Can you share any examples of cross-channel differences?

[On the outbound side] we can vary the message by channel. We can see different preferences across channels and there are some messages that are more cost-effective to deliver electronically than in mail. That goes back to the rules in the [Unica] Affinium software.

On the Web, we use [Visual Sciences’] Web analytics product to understand behavior at very high levels with respect to how people are navigating through the site and how they’re spending their time. We’ve brought all of our segmentation schemes ” the personas and customer value scores - into our Web Analytics so we can understand if a Barry or a Jill is navigating a particular area of the site. We understand where our best customers are spending time on the site and we’re able to translate that, because of our customer database, into an online and offline experience, but we don’t use that to understand individual customer behavior.

The other side of the Visual Sciences tool box we use is the visualization tools. Those sit on top of the customer database and we use them to do very rapid analytics. It almost puts a GUI interface on a big customer database.

Any final thoughts on the importance of cross-channel analysis?

You’re seeing the tools sets begin to come together. When I think about individual customer experiences, each of our channels represents a listening post. Whether it’s a call center or a store or a Web page, I’m listening to the customer tell me something. Ultimately, as these relationships with the customer deepen and as the game changes from acquiring customers to building relationships with customers, you have to figure out how to be relevant to millions of customers at a time.

 可以看到best buy在致力于创建用户统一视图,从客户线上交易数据,线下交易数据,call center 请求服务的数据,产品咨询的数据,网站点击流的日志数据,其他第3方的客户数据(估计是客户背景,收入,职业,兴趣爱好)等等构建一个用户的多方位视图。matt smith举了2个例子,jill和barry,他们的身份背景不相同,购买的目标产品也不一样,如果没有用户统一视图,那么对他们做个性化的营销就很困难。有了用户统一视图,best buy可以知道给特定用户推荐特定商品,比如说你买了家庭影院设备,best buy就会推销环绕音响,清洁电源,通用遥控器。通过从分析用户的各种行为去了解用户并借此提高用户的粘度和购买力度,提供与竞争对手不一样的差异性服务而使企业和用户实现双赢。

NCR TERADATA WORLD

  上周应teradata公司的sales邀请参加了NCR TERADATA 2007年会,说起teradata很多人可能不知道这家公司,teradata的母公司是NCR,它在英汉字典中的解释是National Cash Register (NCR Corp.) (美国)全国现金出纳机(公司),NCR成立于1884 年,主营产品ATM机,POS机都达到全球占有率第一位,借助这两类产品公司NCR也跻身全球500强企业。

  teradata于1991被NCR收购并成为子公司,在此以后NCR充分发挥了teradata的多并行处理能力,使teradata成为了全球最专业的数据仓库厂商,在去年的Intelligent Enterprise 杂志评选中成为全球最佳数据仓库及商业智能设备应用供应商。

   做为数据仓库领域的领导厂商,teradata有众多客户,全球500强第一位就沃尔玛公司就是使用了teradata的数据仓库和CRM系统,C2C行业的龙头EBAY也是使用了teradata,还有不计其数的电信业,银行业的公司也是属于teradata的客户。

   这次在上海举办的teradata 2007年会吸引了600多人到场,会议的主场地在龙之梦丽晶酒店,我们也被安排到了龙之梦丽晶住宿,五星级酒店还真是不错,连打扫的服务员都会说英语。还有一部分人被安排到了绿地豪生酒店,应该也不错。

  我在星期四晚上坐火车到了上海,然后再到酒店已经10点多了,teradata的肖枫在大厅接待了我们,真不好意思让肖枫这么忙,在这里谢谢肖枫了。我们被安排住在了45楼,从来没住过这么高的楼啊。还好那个电梯高级,跟坐飞机似的,半分钟就到了。进房间以后上了会网,看了一会股票就洗洗睡了。

  第2天一大早就起床去吃早饭了,2楼的自助餐厅很有意思,中餐和西餐放得比较远,一眼看去放面包蛋糕的那块都是老外,放米饭,面条这边的黑头发的居多。我跑到老外那块一看,没啥食欲,唉,中国人还是吃不惯面包啊。房间里面的本子上写着自助早餐180元一位,看看好像不值这么多钱,没啥好吃的,就吃了一点米饭,亏了!餐厅的空调打得格外的冷,估计是老外都比较耐寒,黑头发的好像很多都穿着西装也比较耐寒,我穿个T恤冻死了,赶紧吃完就跑房间去了。

  9点钟会议开始了,由teradata大中华区总裁吴辅世致辞,然后由全球总裁Mkie Koehler做主题为“释放企业智能”的演讲,讲的还不错,老外虽然年纪不小了,可是气质还是8错的,ppt里面提到了teradata公司的净利润是30%,这在it企业可是相当高的利润,互联网公司的利润率也不过如此,底下的sales跟我开玩笑说老外这么老实把老底都给漏了,这下卖teradata要被人砍价砍死了。接下来是CTO  Stephen Brobst做主题为“将决策服务整合到实时企业”,中间提到了动态数据仓库的概念,这个也是数据仓库业界最近很火的一个概念。如果摆脱批处理,如何演变到实时加载,实时处理,更加及时的提供服务。从战略决策到战术操作,从分析型数据仓库到操作型数据仓库,Brobst讲的确实有借鉴意义。不过他也免不了打起teradata的广告,号称unix已经消亡,号称专用芯片已经消亡,封闭式系统已经没有出路,未来是intel和amd的天下,而teradata恰恰是采用开放式芯片的,开放式操作系统的开放式平台。这个言论好像有点搞笑,我认为相比起oracle,db2的数据仓库解决方案来说teradata更像是封闭式系统。

  最搞笑的一刻发生在下面,茶歇以后是主题为“助力Teradata释放企业智能”的演讲,演讲人是oracle公司商业智能大中华区总经理湛家扬,teradata和oracle这2家公司互为竞争对手,居然oracle成为teradata年会的金牌赞助商并在大会上发表演讲,这如果是国内的竞争对手公司绝对不可能发生。湛家扬幽默的演讲也给人留下深刻印象,oracle在收购sunopsis,sibel,Hyperion后推出的ODI等产品也表明了oracle在数据仓库领域的决心。

  下午是分会场的演讲,我去听了AT&T,DHL和中国邮政的三个主题演讲,出来以后碰上EBAY的一位同事就交流起来了,大家都是做互联网的自然话题也比较接近,交谈甚欢。因为第2天公司要去外面outing,所以完了以后就直接坐火车回杭州了,没有参加第2天teradata安排的高尔夫,上海,苏州,嘉兴一日游等活动。坐了1个多小时没座位的火车回到杭州后已经饿晕了,老婆一直等到我到家和我一起吃饭,虽然说老公老婆之间不用说感谢,但是在这里也要谢谢老婆一直能这么支持我。回到家收拾了一下公司outing用的行李,等着第2天的象山之行了。象山之行之行很精彩,下一篇blog会写象山之行见闻。

黑狱拳霸 I II

图片点击可在新窗口打开查看

上次淘了黑狱拳霸 1,2两本D9 DTS的碟,虽然两本片子看起来像续集,但是实际上剧情是独立的,主演也是不同的人。黑狱拳霸1的话主要内容讲的是世界重量级拳击冠军“冰人”乔治威廉(Ving Rhames饰)因为强奸罪被判入狱,在监狱里面遇上了另一个不败的监狱拳王蒙若赫臣(Wesley Snipes饰,演刀锋战士那哥们),在狱中黑手党老大的安排下进行了一场拳赛。一部典型的美国影片,hit-pop,到处可见肌肉,监狱,黑手党,各种美剧的必要因素都在里面了。冰人的角色并不讨好,非常嚣张,狂妄自大到令人讨厌,一进监狱就挑衅蒙若,相比较而言因为老婆偷情失手打死老婆情人而进监狱的蒙若性格好像很沉稳,看起来很像正面人物,估计是Snipes的名气比Rhames大的多原因。看完以后很容易就能知道这部影片其实是在影射美国前重量级拳王迈克.泰森,影片充斥了对迈克.泰森的讽刺,虽然影片情节比较简单,但是拳击片断还是比较专业,DTS的音响效果也还算可以,所以也还算一部值得一看的碟片。

相比较黑狱拳霸 1来说,黑狱拳霸 2的情节基本上跟迈克.泰森毫无关系,2里面的主角虽然还是叫”冰人”,但是这个冰人就充满了正义感,首先入狱是因为被人陷害,其次入狱以后种种表现都体现出正义感,尤其这黑哥们长得也挺帅,让人一看就知道这位是主角。监狱拳王也蛮帅的,那腿功就跟李小龙似的,但打斗时极其残忍,一看就知道是反面角色。最终也是安排了一场拳赛,正义战胜了邪恶。第2部的我个人感觉比第一部好看,演员看着比较顺眼,动作漂亮,情节比第一部要曲折,对于主角人性的刻画也比较有力度。对于一部小成本的电影来说,能拍成这样还算不错。
