Data quality isn’t fixed. Depending on the

hypothesis, a single data set can shift from

useless to incredibly insightful without a

single datum changing shape, size, form, or

function.

#1 Data is subjective

Claim 1: Data quality is destroyed

by laziness and lack of ambition.

Claim 2: A TMS empowers

developers more than others.

The root of all evil


The root of all evilThe "project"


Your organization is creating absurd

amounts of data with every passing second,

and it’s very difficult to adapt to the fluctuations

without an agile, process-driven mindset.

#2 Data is a process

The project is often a series of handovers,

breeding non-involvement.

This leads necessarily to silos, which have entry

and exit conditions.

Data is the lifeblood of the organization. It flows

through all departments, across job titles,

permeating the very fabric of the organization,

reinforcing its foundations for growth.

#3 Data abhors silos

Do these sound familiar:

Monthly reports which lack relevance, are rife with generic suggestions that lack research in the context of your business, reiteration of previous month’s points, even if there are

solid reasons why they weren’t addressed.

Ridiculously ugly and ineffective JavaScript hacks for measurement points which should be tackled in the Data Layer.

Hiding behind data, and passing blame to other silos.

Could someone fix the Bounce Rate metric on our

site?

Analytics feature requests are deprioritized, and deployed extremely infrequently.

Fix transactionRevenue to show revenue, not

customer weight.

Communication is difficult due to the overhead of meeting face-to-face, project plans are set in stone during sales, and it’s difficult to change existing project goals or set new ones

due to consultants being hired as "extra pairs of hands" rather than advisors.

These are symptoms of data being treated as a

project outcome.

Cure I: The Data Layer


Cure I: The Data LayerUsing technology to solve communication problems


Typically, there are three definitions

of Data Layer that we use in the digital world.

1. Set of business requirementsfor tracking digital assets,visits, and visitors.


2. Encoded, global data structure, accessed and modified by connected platforms.



2. Data model of a connected platform, which copies or digests information in the global structure.



2. Data model of a connected platform, which copies or digests information in the global structure.

dataLayer.push({ 'pageType' : 'home' });

google_tag_manager['GTM-123'] .dataLayer .set('pageType', 'home');

Across all three definitions, the purpose of a Data Layer

is simple:

DMP / DWH / TMS / etc.

The purpose of a Data Layer is to provide a bilateral layer on the digital asset, which decouples, normalises, and uniformly encodes semantic

information passed through and stored within.

The Data Layer is a joint venture, where people and

systems communicate across silos.


let tracker = GANTracker.sharedTracker() tracker.trackEvent("revenue", action:"Q1", value:"15678000") tracker.trackEvent("revenue", action:"Q2", value:"16888000") tracker.trackEvent("revenue", action:"Q3", value:"15991000") tracker.trackEvent("revenue", action:"Q4", value:"19133000")

let dataLayer = new Array()dataLayer.push({ "revenue_Q1_2014" : "15677998.00", "revenue_Q2_2014" : "16887988.00", "revenue_Q3_2014" : "15990988.00", "revenue_Q4_2014" : "19133400.00"})

An iterative, agile process is necessary for

optimal utilization of a TMS.

requires knowledge and expertise to manage.

Developer facilitation is crucial to data quality

and optimized data collection.
