The Missing Metric: ROI

by on April 11th, 2012

Metrics are essential measurements to determine if a project is meeting the established goals of time, delivery and budget constraints.  This may be a bit off the requirements blog norm, but worth the mention.

There has been a change in the market where the ROI (Return on Investment) is not a requirement in the eyes on projects.  Is the ROI forecast replaced by a focus upon the financial burn? Are people considering what was spent to arrive at the solution and counting up the cost after the fact?  It is important to track what was spent and if the project arrived on, under, or over budget.  Some organizations are of the thought, “Just track the burn.”  Financial disaster, monetary suicide, bad judgment, new line of thought; you be the judge.

In these troubled financial times when institutions are trimming the fat and jobs, not laying the foundation of financial success can be the road to financial ruin.  There are some necessary projects where the ROI does not have the deciding impact but when it becomes company standard not to have an ROI there is a backlash to pay.  The focus of the “get the most for the dollars spent with the best solution” is vanishing in some firms because the preverbal purse strings are open.  What happens when the well runs dry?

Is sober financial planning disappearing?  The ROI is a metric norm to follow and it appears it is giving way to the free will spend, spend, spend until it is gone.  There’s a new program to align with without the old metric.  ROI is worth the effort, right?

Writing Business Requirements – The What

by on March 5th, 2012

Details, details, details; it is in the details.  Details explain to the point so the “what” is not misconstrued. Explaining the details create the pain staking exercise of placing the future state of a project on paper before design starts. It is worth more effort than a theoretical paperweight, along with wasted time being grilled by a room of design/system personnel to uncover the “what.”

Details give the advantage of listing specifics to create a picture of a well-defined outcome. Specific details on a form include: name in the top right corner, account number left margin, indentation above the name, etc..  General statements in requirements only cause additional discussions during fact-finding sessions, which is something that can be avoided.  For example, stating a requirement that says, “Demographic information must be collected and stored in a central location,” will incur discussions because a general statement is just that: a general statement and not a true requirement.  Questions like, “What demographic, patient, vendors, doctor, associate, site location, sales region, third party are desired?”  Drill down to specifics: first name, last name, middle name, phone, address (street, state, zip, and country), measurements (length, width, depth) and so on.  Specifics provide a commodity savings (time!) for later use. Time is the one resource that once used cannot be regained.

Another example, heard most often from the young at heart, is “I want a car.”  No specifics, just “I want a car!”  Take the youngster to a junk yard and present the cars.  The shock value  will bring out the details of make, model, year, exterior/interior color, style, engine size and gas consumption. So plan, review, and craft the details or get ready to have numerous fact-finding sessions.

Business Requirements: Don’t Say “How”

by on February 6th, 2012

Stating how to achieve a result is normally taboo in requirements writing. The resounding “No” that causes systems personnel to cringe is when someone wants to dictate how to perform a task in business requirements. This temptation, to which multitudes fall prey, causes the undoing of a requirement.  There are times when it’s absolutely necessary to state the how to of a requirement but, in general, business requirements should state what is desired, and not how to achieve the results.

Simply put, children can be our best teachers when it comes to writing requirements. They often declare what they want without concern for how to achieve the results.  It echoes throughout stores, “Mommy, I want this,” or “Daddy, I want that.” Somehow, we never hear a child say things like, “you know, you can use the savings account, or the checking account, or your credit card to obtain this particular item.”  Children don’t care how we get the bear or bubblegum; cash, credit, barter or trade makes no difference to them. Just get the toy, or in these days of electronics, the iPod, tablet, computer, computer game or the newest cell phone with apps.

The reason not to say how is that it confines developers/system personal to limited functionality within a limited spectrum while other methods are feasible and may yield faster results with added value and significant quality.  Technology changes at a blinding rate; thus, what is known by business partners as ‘cutting edge’ can change within months.

I’ll close with a couple of examples:

1) Business partners wanted data displayed, but stated how by dictating the use of a familiar legacy system.  Immediately, conflict and confusion arose, because the legacy systems were in transition and system personal were feeling obligated to either use legacy or develop an explanation of why the legacy systems were not part of the new system architecture.  The project stalled and gave way to discussion of the legacy system verses new architecture and explaining the benefit of using the new architecture. In the end, the legacy system was shutdown.  The discussions hampered progress and the time lost is a resource not regained.

2) One method of stating what to do without confining resources is to state, “The system shall,” and to explain what the system should perform. “The system” is a generic term that offers uninhibited functionality and liberates personnel in solution development.

Requirements: The Good, the Bad and the Ugly

by on January 11th, 2012

Welcome to 2012, a new year of projects and a good time to discuss the topic of requirements. With the advent of any project, there are foundational constraints a project is assembled to communicate an end purpose. Healthcare organizations are finding themselves swamped with IT projects these days.  Many are grabbling with EHR, ICD-10, Business Intelligence, and the like.  However, whenever considering these IT projects, one must consider the requirements.

Like the rebar in cement or the laminin protein cell’s importance to the human body, requirements are what give a project a cohesive launch point.  The art of writing good business requirement is found in declaring “what” is desired with as much detail as possible without stating “how” to achieve the “what.”  Having worked on both side of the project table, Business and System teams, has given me a well round view in regard to the gathering and documentation of business and system requirements.

This a first in a five part series surrounding writing sound, concrete requirements, how to identify and recover from the poorly written and employing techniques to gather aspirations.   It makes good sense to do the research into “what to achieve” and here’s why.  Requirements, depending upon how well they are written and/or researched,  can give a project an ease of understandability or dispense an undercurrent  to slow progress to the speed slower than an earth slug or worse, ensue confusion to halt project momentum and cause tempers to flare!

As said many times “What does not kill us, only makes us stronger,” and to many, writing requirements is a painful undertaking.  The challenge comes with the following:

  • Stating the not-so-obvious and relaying statements to others – seeing through another’s eyes
  • Stating the “WHAT,” the end results – the goal to achieve
  • Stating the “WHEN,” – better known as the SLA (Service Level Agreement) – the speed in months, weeks, days, hours, min, or seconds a goal is delivered
  • Resisting the temptation to state “HOW” to achieve the “Desired WHAT”

My point is that my involvement in projects has more than exposed me to the Good, the Bad and the Ugly of requirements and how to turn the Bad and Ugly into the Good.

I welcome your views of requirement gathering as I move through the dialogue of the “WHAT,” the “WHEN” and techniques to gather and document requirements.
