A Scraps-Free New Year

As chances are for new years to come with the legacies of past ones, that would be a good time to scrub the scraps.

How to scrub last year scraps (Subhod Gupta)

Legacies as Forced Reuses

As far as enterprise architectures are concerned, sanguine resolutions or fanciful wishes notwithstanding, new years seldom open the door to brand new perspectives. More often than not, they bring new constraints and further curb the possible courses of action by forcing the reuse of existing assets and past solutions. That will call for a review and assessment of the irrelevancies or redundancies in processes and data structures lest they clog the organization and systems, raise entropy, and degrade governance capability.

Architectures as Chosen Reuses

Broadly defined, architectures combine assets (physical or otherwise) and mechanisms (including organizational ones) supporting activities which, by nature, must be adaptable to changing contexts and objectives. As such, the primary purpose of architectures is to provide some continuity to business processes, across locations and between business units on one hand, along time and business cycles on the other hand. And that is mainly to be achieved through reuse of assets and mechanisms.

Balancing Changes & Reuse

It may be argued that the main challenge of enterprise architects is to maintain the right balance between continuity and agility, the former to maintain corporate identity and operational effectiveness, the latter to exploit opportunities and keep an edge ahead of competitors. That may turn to be an oxymoron if architects continuously try to discard or change what was designed to be kept and reused. Yet that pitfall can be avoided if planting architectures and pruning offshoots are carried out independently.

Seasons to Plant & to Prune

Enterprises life can be set along three basic time-scales:

  • Operational: for immediate assessment and decision-making based on full information.
  • Tactical: for periodic assessment and decision-making based on partially reliable information. Periodicity is to be governed by production cycles.
  • Strategic: for planned assessment and decision-making based on unknown or unavailable information. Time-frames are to be governed by business models and risks assessment.

Whereas architecture life-cycles are by nature strategic and meant to span an indefinite, but significant, number of production cycles, trimming redundancies can be carried on periodically providing it doesn’t impact processes execution. So why not doing the house cleaning with the beginning of new years.

    Very thoughtful. Renovations (including discarding & pruning) and Reuse are both required as web and woof of enterprise fabric. Surely they must be balanced.

    If the life spans of designs of organization, processes (including rules, methods and procedures) are too long and tend to be irrelevant or obstructive, it is desirable to set expiry date on them. If any of them are sought to be continued they should go through a process of evaluating and approving new designs /implementations to avoid bias (lethargy) of doing things in a particular way, only because they had been used that way for some time.

    This will enforce freshness without discarding useful maturity, stability and continuity.

    This spurred me to discard a few physical things that got accumulated for years and are never used.

    Hai Remy:   Thanks for the Blog.   I liked it and posted my comment.  I hope you will find it relevant and useful. In a different contest there was a question: What constitutes work or process? or what is a unit of work or a process?  Reflecting on it I concocted that A unit of work is anything a single performer can carryout without a break (pause is ignored) due to critical external dependency or a need to change of place of work. I recall you cited an age-old principle used in plays and dramas which essentially means what I concocted.  I request you to kindly quote and give the reference. Thanks and regards, MERRY CHRISTMAS and HAPPY NEW YEAR 2015
