Introduction

Through "LYNX TameFlow Buffer Management" the benefits of Buffer Management become also available for teams and team members working with cards on the LYNX TameFlow Taskboard(s).  

LYNX TameFlow Buffer Management prevents multi-tasking and guides Teams and Team Members to select the next card to work on, based on a clear priority, generated through buffer management. 

The following options are supported:

• Buffer Management Types:
  • Workpackage Level (for Workpackages integrated within projects)
  • Card Level (for single Workpackages for managing services workflows)
• Buffer Calculation:
  • Fixed (Card Types have a fixed card size (e.g. 2 days) and services time e.g. 3 days)
  • Dynamic (a buffer time is calculated dynamically, given a card size estimate, expressen in hours)

This article introduces "Dynamic TameFlow Buffer Management" with Management Type "Workpackage Level" and "Dynamic" Buffer calculation. Refer to this section to learn more about the other combinations and possibilities. 

 

Card type configuration

In this example the Card type "Subtask w/ buffer management" is created. The first step is to create a Due date field via the Unit-of-Measure table. 

Create a Due date field

Create a Due date field as follows:

 

Create a new Card type and select fields

For this example the "Subtask w/ Buffer Management" card type is created. Select the Due date field and its Property type:

Configure Buffer Management

Configure Buffer Management as in the picture below. 

The Dynamic Buffer Size percentage has been set at 50 %: if the Original Estimate is 16 hours, 8 hours (50%) buffer will be added to the Service level window of the card. This window is 16 + 8 = 24 hours, is 3 days duration.  This means that if a Card is started on Monday morning, the Due date will be set at Monday morning + 3 days = Wednesday afternoon.

 

 

Add a Workpackage with some Cards

Create a Project and add a Workpackage 

First add a new project:

Add a Workpackage as well: 

And add some cards and their estimates:

Subtask A has a size of 16 hours → its service level window is therefore 16 hours + 50 % = 24 hours (3 days).  Subtask be has a size of 32 hours → its service level window is therefore 32 hours + 50 % = 48 hours (6 days).

Prepare for getting Cards Done with TameFlow Buffer Management

Add a Project Buffer (Optional)

By default the CCPM scheduling engine is switched on, which allows you to add a project buffer, using the CCPM dialog boxes. You may also skip inserting a project buffer. 

Distribute Cards to the Taskboard of Mike Dempsey

The following conditions for showing cards on the Taskboard of Mike are applicable:

• Configuration:
  • Mike must exists in LYNX as a user and have a "role" that grants him access to the Workpackage when it is published in other screens (My activties and Taskboard). In this example the role of  a "Resource User" is assigned to Mike via the "Resource Table" .
• Process conditions:
  1. the "Project Status" should be set from "Not started" to "Released"
  2. Mike should be assigned (or confirmed) as a resource to the Skill Designer for "This is a Workpackage" 
  3. the Workpackage status should also be set to "Started"

 

Get Cards done with LYNX TameFlow Buffer Management

Open LYNX TameFlow

Open LYNX TameFlow again (see this article: Get Cards done with the LYNX TameFlow Taskboard or Cards View).  

Start Subtask A by moving it to the next column (in Progress).  At the moment the card is started LYNX will update the initial (default) due date of 27 November.  

Note that each card within a Workpackage gets the same initial and default due date, which is the scheduled stop date of the Workpackage when it was set to started (see above). 

The picture below shows the buffer status at +1 day  (Tuesday) → one day of buffer is consumed: the TameFlow buffer colors Orange:

Start now also Subtask B and review the calculated due date → Today + 6 days:
