Although each workbook is set up with default themes, the look and feel of SLIM-Estimate, SLIM-Control, SLIM-Metrics, and SLIM-MasterPlan workbooks are readily customizable.  

Screen Background

The easiest way to change the feel of your workbooks is to change the background color and style.  To change the background color, go to Tools|Customize Display|Screen/Printer Fonts, Colors, and Symbols…, then go to the Colors & Symbols tab on the right.

Color Start and Color End are important if you want to create a gradient background, like the background in the first image.  A gradient background begins with your specified Color Start color then transforms into your Color Stop color either vertically, horizontally, or diagonally (pictured above).  If you choose the Solid color style, simply select your Color Start.

Graph Background

Like the Screen Background, you can have a solid background or a gradient.  Simply follow the steps above for selecting your colors and styles.

Solutions and Reference Data

In the previous articles in this series I presented SLIM-Estimate’s use of uncertainty ranges for size and productivity to quantify project risk, and how to build an estimate that includes contingency amounts that cover your risk exposure.  In this post I will identify the project work plan reports and charts that help you manage the contingency reserve.  You will see how to use SLIM-Control bounds and default metrics to keep your project on track. 

Understand the project work plan documents.

In our example so far, you have estimated a project to deliver a software product in 11.7 Months, with a budget of $988,223.  This estimate includes an 80% contingency reserve, or risk buffer, on both effort and duration.  Your work plan is based upon SLIM-Estimate’s 50% solution; 11 Months and $755,400.  Thus, the uncertainty about size and productivity are accounted for; it is built into your plan.  The probability that you will meet the project goals is driven by many factors ‒ too many to measure.  You can only manage what is within your control, and escalate issues so they can be resolved in a timely manner.

Managing the project well begins with a solid understanding of the detailed project plan.  SLIM-Estimate provides several default and customizable charts and reports that document the plan.  Here are a few key reports¹ to study in order to identify the core metrics you will want to monitor closely.

Several months ago, I presented SLIM-Estimate’s use of uncertainty ranges for size and productivity to quantify project risk.  Estimating these two parameters using low, most likely, and high values predicts the most probable effort and time required to complete the project.  This post shows you how to use SLIM-Estimate’s probability curves to select the estimate solution and associated work plan that includes contingency amounts appropriate to your risk.

Begin with an unconstrained solution

The default solution method used for new estimates, whether you are using the Detailed Method or another solution option, is what we call an unconstrained solution.  Just as it sounds, no limits have been placed on the effort, schedule, or staffing SLIM-Estimate can predict.  It will calculate the resources required to build your product (size) with the capabilities of your team (PI).  Assuming you have configured SLIM-Estimate to model your life cycle and based your inputs on historical data, you have produced a reasonable, defensible estimate.  

“The only thing that is constant is change” ~Heraclitus

This proverb is often told to individuals (like me) who love to see a project follow a plan from start to finish.  I’ll be honest, I’m a planner. I’m thrilled when the plans I put in motion actually work out the way I intended.  These are the moments when I retort, “the only people who like change are wet babies.” However, more often than not, something changes, which throws off my entire plan and forces me to not only revisit Heraclitus’s proverb but also rethink my plan entirely.

Building software, particularly in Agile development, is no exception. In fact, the second principle of the Agile Manifesto states that developers should: “Welcom[e] changing requirements, even late in development. Agile processes harness change for the customer’s competitive advantage.”

It would seem, then, that this principle would disappoint any planner working on an Agile team. Why bother creating a development plan if you know the stakeholders are going to change their minds about their desired features at the last minute? While we’re on this subject, if the requirements are going to change from one iteration to the next, why bother estimating the project at all?

After one particularly difficult midterm in college, my professor said, "This is just a wakeup call; there's still time to improve before the final." I think that wakeup call was particularly painful, but my professor's words stick with me today, especially when thinking about data collection (or lack thereof) when a project is over.

As someone who is not a project manager, it was difficult for me to understand why project managers would not collect their own historical data. I understand now that after a project is finished, people move on to the next project and there's no time to update project stats. Recently, I read a post on Gantthead.com by Kenneth Darter called, Project Closure: Party or Post-Mortem?. Darter says if the project was a success, then it's important to record why it was successful; if the project was not successful, it's important to capture why it was not successful.

The word "data" in Latin literally means "things having been given." At the end of a project, you have been given a lot of things that only you and your team know: size, effort, duration, staffing, PI, cost, etc. If you are able to take a moment to fully document your project information, you not only build a historical database, but you're able to reflect back on that project to improve future endeavors (whether you would like to remember it or forget it completely). Darter recommends creating a checklist which, "should be defined early on in the project and communicated to everyone who will have input into the checklist at the end of the project." In addition to project specific information, he specifically recommends these three items:

I am often asked this question during SLIM Training classes.  I remember wondering about that myself.  It is a logical question since SLIM-Estimate workbooks are often imported into SLIM-Control to create the baseline project plan.  The answer is ‐‐ they are not directly related, because uncertainty ranges, probability curves, and control bounds are designed to perform different tasks.  This post is the first in a series looking at risk associated with an estimate, risk of your project plan, and handling deviations from the plan.

What are we talking about?

The first thing we need to do is define some very important terms that are often misused (I am the first to admit I have been guilty!).  I went to good old Dictionary.com and looked up the following:

After being away from QSM and the software world for three years, I was blown away by SLIM v8.0's dynamic product integration. I knew it was coming, yet I was still impressed by the simplicity and power of analysis promoted by real-time data and tool links across the SLIM Suite that frees managers to focus on the important program issues.

SLIM-MasterPlan is the center of the SLIM Suite product integration.  It improves upon previously existing program management features of aggregating multiple SLIM-Estimate projects and ancillary tasks with two new capabilities: 

• Linking SLIM-Control workbooks to provide real-time project tracking and control at the program level 
• Performing What If analysis at this higher management view to consider a wider range of potential outcomes.

The What If analysis feature is what I want to highlight.

A good personal development coach knows the "power of the question."  Questions lead to discovery, innovation, and action that brings about positive change.  Better questions lead to better answers.  SLIM's power and distinction has always been fast and easy evaluation of the impact of change, and exploring the realm of possible outcomes.  That's what we are doing when we ask ourselves "What If…?" (or our boss asks us - and we better know the answer!).  SLIM's solution logs make it easy to compare estimates, plans, and forecasts to alternative solutions, QSM trends, and your historical project database.
